Colorful Tropical Hibiscus

Hibiscus rosa-sinensis 'Chiffon Breeze' (TRADEWINDS™ CHIFFON BREEZE, TRADEWINDS™ BREEZE SERIES)
Hibiscus rosa-sinensis ‘Chiffon Breeze’

Giant blooms bursting with color—these make Chinese or Hawaiian hibiscus (Hibiscus rosa-sinensis) a floral favorite in sizzling summer gardens. Huge variety is another perk of these tried-and-true tropical shrubs. There are literally hundreds of types that come in many floral color variations and sizes. And, their familiar good looks bring to mind Hawaiian shirts, leis, and landscapes. What’s not to love?
Native throughout tropical Asia, these hibiscus have been bred for centuries for their big, beautiful flowers. Through woody, they are fast growing and ever blooming, making them ideal for large patio containers and bed plantings. Their lush, deep green foliage creates a perfect foil for the big beautiful flowers. Some leaves are even glossy. These plants are only hardy in USDA Hardiness Zones 9-11, which means they will only survive winters in the most southerly regions of the United States. But, they will overwinter well in a sunny, warm indoor location where winters are cold. A bright south-facing window, sun room, or conservatory is perfect.

The flowers are between 4 and 8″ wide and comprised of five large, open petals. The largest varieties are the size of dessert plates. They come in loads of bright, tropical colors to include all shades of pink, red, orange, yellow, and white. Unusual colors, such as near black, gray, and purplish hues are also common. Many blooms are bicolored and tricolored, with radiating rings of bright color. At the center of each bloom is a protruding pistil lined with colorful stamens, which is attractive and interesting in its own right.
There are literally hundreds of varieties of Hawaiian hibiscus. The International Hibiscus Society has a full register of every type under the sun. Anyone interested in learning more about these beautiful flowers should have a look. The wide ranging varieties give a complete picture of all this plant has to offer. To get a good look at exciting newer, interesting selections, check out the offerings of specialty growers, such as Charles Black’s Hidden Valley Hibiscus. His amazing hibiscus may be just enough to hook you!
Garden center varieties are often bred for compact habits and high flower production. The Tradewinds varieties are particularly nice, being developed to produce lots of flowers on tidy plants ideal for container growing. Though the plants are small, they always grow and flower best in large containers that allow their roots to spread and easily access water and nutrients. Large containers also need to be watered less often.

Grow these beautiful flowers anywhere there is sun. They prefer fertile soil that drains well and perform best with some supplementary fertilizer for flowers. Starting with a fortified potting mix, such as Black Gold’s All-Purpose Potting Soil with RESiLIENCE, is a good idea. Potted plants appreciate large containers and will fill them in quickly, if plants are happy and well-tended. In warmer zones, these shrubs are best planted in garden and shrub borders mixed with other lush, tropical plants loaded with bright color.

Fantastic Fragrant Garden Flowers

By the end of winter, gardeners long for the sweet scents of flowers.  Some of us take solace in cut flowers from the florist or supermarket while thumbing plant catalogs and indulging in flowery daydreams.  Convert those daydreams to reality by planning a few fragrant garden flowers to your beds, borders and containers.

Scents of Early Spring

Daffodils (Narcissus spp.) are the essence of spring and some varieties are delectably fragrant.  ‘Campernelle’ is one of them, a multi-flowered yellow species narcissus that blooms early and gracefully.  Towards the end of the daffodil season, luxurious ‘Rose of May’, a double-flowered white bloomer, lives up to its name, exuding a sweet scent.

The legendary courtesan, Madame Pompadour, loved hyacinths (Hyacinthus orientalis) and nearly three centuries later, they still carry the fragrance banner into mid-spring, with stocky heads of highly scented florets in an array of Easter egg colors.  At about the same time, intensely fragrant lily-of-the-valley (Convallaria majalis) scent shaded places with their unique “Muguet des bois” aroma, long a favorite of perfume makers.  If you already grow lily-of-the-valley, dig up a budded clump, pot it up with some Fafard Natural and Organic Potting Soil and enjoy the fragrance indoors while the flowers last.  Afterward, return the clump to the garden.

Late Spring Fragrance

In pots or trained against walls or trellises, old-fashioned annual sweet peas (Lathyrus odoratus) send out a ravishing scent.  The maroon and purple Cupani types are among the most fragrant, but all varieties please the nose while tantalizing the eye with delicate orchid-like flowers.  Get a jump on the season by starting sweet pea seeds indoors in trays or cell packs filled with Fafard Natural and Organic Seed Starter.

By late spring, fragrant garden peonies (Paeonia lactiflora) command center stage, with tall stems, handsome dissected leaves, and big, bountiful flowers.  Older varieties, like the rose-pink double, ‘Sarah Bernhardt’, offer winning fragrance and make excellent cut flowers as well.  Well-tended peony plants will live for decades in the garden.

Summer Scent Extravaganza

Sweet scents abound in summer.  Biennial stocks (Matthiola incana) are sun lovers that grow one to three feet tall and bear colorful, dense clusters of spice-scented flowers.  Carnations (Dianthus caryophyllus) echo that clove fragrance, with familiar ruffled flowers in single and bi-colored combinations of reds, whites, yellows, pinks, and purples.  Both stocks and carnations can be grown from seed started indoors eight to 12 weeks before the last frost date, but are also available from nurseries in starter packs.
Standing tall at the back of the early summer border, nothing perfumes the air like Oriental lilies (Lilium spp.).  Hybridized from several different Asian lily species, Orientals grow three to four feet high and may require staking.  The effort is worth it to support the enormous scented trumpets that are borne in profusion on mature plants.  Freckled pink ‘Stargazer’ and pristine white ‘Casa Blanca’ are among the best-known Oriental lilies.

Evening Stars

Nicotiana 'Domino White' (DOMINO SERIES)
The Nicotiana alata hybrid ‘Domino White’ scents the air on summer nights.

Fragrant night-blooming plants open their petals in the evening hours to attract pollinators.  One of the best is flowering tobacco (Nicotiana alata), which bears long tubular flowers that flare into white or yellow-green trumpets.  Look for the fragrant species form, rather than unscented hybrids, and plant near seating areas or paths where evening visitors can enjoy them.

Fall Scents

Fragrance is harder to find as the growing season winds down, but plants that provide it are worth seeking out.  Perfume shady spots with cimicifuga, sometimes known as black cohosh or bugbane (Actaea racemosa).  Rising four to six feet tall, Cimicifuga bears elegant, deeply dissected foliage.  Sweet-smelling white flowerheads, each one bearing scores of tiny fragrant blooms, wave high above the leaves in the early fall.
Dahlias are great garden and cutting flowers, but are not known for fragrance.  It pays to plant the few that combine beauty and 'Honka' dahliascent.  ‘Honka’ is one.  Thriving in sunny spots, the single flowers sport eight narrow yellow petals apiece.  The combination of beauty, scent, and hardiness won ‘Honka’ the Royal Horticultural Society’s coveted Award of Garden Merit.

Location is Everything

Position fragrant flowering plants strategically throughout the garden and combine them with a selection of shrubs, trees and foliage plants that also exude distinctive scents.  Even weeding seems easier when the fragrance of flowers hangs in the air.

Annuals for Fantastic Fall Color

Many gardens lack for fall color – prompting many gardeners to resort to the ubiquitous fall mum.  Often overlooked, however, are the numerous other annuals for autumn display, many of which come into their glory months before chrysanthemum season.  Their beauty, longevity, and relative novelty make them a refreshing and often preferable alternative to what has become a fall garden cliché.

Chinese Hound’s Tongue

The dazzling, October-sky-blue flowers of Chinese hound’s tongue (Cynoglossum amabile) give the impression of a tall, out-of-season forget-me-not (Myosotis).  In all respects, however, this biennial outshines its spring-blooming cousin, possessing a much longer, summer-to-fall flowering season, as well as attractive, fuzzy, gray-green basal leaves that persist rather than turning to mush.  Sown directly in the garden in spring, it will bear a late-summer to frost succession of clustered blooms on upright stems.  Plants usually self-sow, but not with the prolific abandon of forget-me-not.  Available as seed or occasionally as plants, Chinese hound’s tongue is typically sold in the form of dwarf varieties such as ‘Firmament’, which top out at about 15 inches.  It reaches its zenith, however, in full-size forms (including ‘Blue Showers’), which can reach 30 inches tall.  This East-Asian native takes well to sunny or partly shaded cottage gardens and mixed borders, partnering beautifully with Japanese anemones, colchicums, and other late-blooming perennials.  Dwarf forms do nicely in containers as well as in the open garden.

Woodland Tobacco

Salvia elegans 'Golden Delicious'
Beautiful red flowers and golden leaves make Salvia elegans ‘Golden Delicious’ a great sage for season’s end.

There’s nothing dwarf about woodland tobacco (Nicotiana sylvestris), a lordly, bold-leaved, delightfully shaggy plant that holds slender silky-white trumpets on lofty stems that look you in the eye.  Blooming alongside (and above) Chinese hound’s tongue from summer to fall, this heat- and sun-loving tender perennial is also a reliable self-sower, with spontaneous seedlings almost always appearing in spring.  Debuting in mid to late summer and continuing in abundance until frost, the flowers cast an intense, intoxicating, musky-sweet perfume that peaks at night, drawing pollinating moths.  Hummingbirds visit during the day.  Plants can be started from seed sown under cover in early spring, or in the garden at tomato-planting time.  Seedlings (which are sometimes available from nurseries) should be planted out after the last frost date.  Fertile, moist soil is best.

Butter Daisy

For containers and other niches where something more chrysanthemum-like is desired, butter daisy (Melampodium paludosum) is just the ticket.  Low, mounded, bushy, and brassy-flowered, it envelops itself with petite golden-yellow daisies for many weeks beginning in summer.  Seed catalogs and nurseries sell numerous compact varieties, all of which form tight, 8- to 12-inch hummocks of oval, weakly toothed, mid-green leaves, with flowers appearing about 3 months after sowing.  Given a fertile, not overly dry soil, plants will continue blooming profusely until the first heavy frost.  Native to Mexico and Central America, this annual can take the heat and will seed itself around in warmer gardens.

Fall Salvias

Mexico is also home to several cold-tender, shrubby sages notable for their showy late-season bloom.  Among the best are Salvia greggii and its hybrids, which throw numerous spires of richly hued, hummingbird-thronged flowers from late spring until frost.  Cultivars include compact ‘Ultra Violet’ , with vibrant rose-purple flowers on 18-inch stems, and the fiery-flowered ‘Furman’s Red’, whose cherry-vermillion wands can reach 3 feet tall.  At least a dozen other tender Salvia species are indispensable contributors to the fall (and summer) garden, thriving in any well-drained, reasonably fertile growing medium, preferably in full sun.  Salvia elegans ‘Golden Delicious’ is a gold-leaved, red-flowered selection with a, particularly beautiful fall display. Most of the shrubby salvias perform splendidly in containers as well as in the open garden, and a few will survive USDA Zone 6 winters.

Beta vulgaris ssp. cicla 'Ruby Red'

Red Fountain Grass

The arching, brown-purple leaves of red fountain grass (Pennisetum ‘Rubrum’) make the perfect foil to salvias and other bright summer- and fall bloomers.  Tawny, purple-tinged, plumed flower spikes arch above the foliage in summer and fall.  Thought to be a hybrid of Pennisetum setaceum (although usually listed as a cultivar of same), ‘Rubrum’ rarely self-sows, unlike its prodigiously fertile parent.  At 3 to 4 feet tall and wide, it works wonderfully in large containers or mixed plantings in full sun or light shade.  Typically grown as an annual, it’s a hardy perennial in USDA Zones 9 and warmer.

Swiss Chard

The roster of showy-leaved fall annuals also includes several varieties of chard.  Sow the seeds in summer for a fall display of large, crinkled, often bronze-suffused leaves, with vividly contrasting ribs and veins.  Most named varieties (such as yellow-ribbed ‘Oriole’ and burgundy-ribbed ‘Rhubarb’) feature one contrasting color, but the mix ‘Bright Lights’ contains numerous hues including red, yellow, orange, purple, and creamy white.  Chard’s close cousin, the beet, has also given rise to some showy-leaved varieties.  Among the most notable is ‘Bull’s Blood’, whose deep maroon leaves make for good eating as well as for good ornament.  As with chard, plants mature in fall from a summer sowing. and provide a welcome change of pace from ornamental kale.

The Summer Garden Harvest Revs Up

As summer starts to wind down, the harvest revs up. August finds many gardeners harvesting daily, as the hard work of spring and early summer is transformed into bountiful crops. Vegetables, fruits, and herbs hover at the peak of ripeness, almost crying out to be picked. Flowers can be dried for winter arrangements and next year’s garden waits in the wings in the form of seeds ready for collection. In the midst of all that abundance, the biggest challenge maybe finding time to capture and process the plentiful harvest while keeping the garden productive well into fall.

Vegetable Harvest

Tomatoes, squashes, eggplant, peppers, beans, cucumbers, broccoli and a host of other summer vegetables require regular harvesting to keep plants productive. Earlier generations of gardeners spent late summer afternoons, evenings and weekends canning or drying the surplus produce. These techniques, plus freezing, are still an option, but so is donating extras to local food pantries or soup kitchens. Non-gardening neighbors may appreciate gifts of fresh produce as well.

In between harvesting sessions, keep production high by enriching the soil around plants such as cucumber, squash, and broccoli with fertilizers like Fafard Garden Manure Blend or Fafard Premium Natural and Organic Compost Blend. After mid-August, gardeners in northern areas with short fall growing seasons should remove excessive bushy growth and flowers from tomato plants, so the plants’ energies go into enlarging and ripening existing fruits before frost.

Herb Harvest

Harvest herbs, especially vigorous types, like basil, regularly, to ensure a continuing supply of young leaves. Cut off any flower stalks as soon as they appear, because the flowering process gives herbs a bitter taste. If plants have become leggy or unwieldy, cut them back by about one third, to stimulate bushy new growth.

Harvest herbs in the early morning, after the dew has dried. The easiest way to dry parsley, sage, rosemary, lavender, and other herbs that are shrubby or have a relatively low moisture content, is to hang cut stems upside down in a warm dry place. Basil and other mint family members with higher moisture levels dry best when the leaves are separated from the stems and arranged on trays to dry. All herbs are ready to store when the leaves can be crumbled easily.

Oakleaf Hydrangea
The aging blooms of oakleaf hydrangea turn pink as they dry and are great for cutting.

Fruit Harvest

August is the time to harvest figs, some melon varieties, late-bearing blueberries, everbearing strawberries, plums and even the last of the cane fruits, like raspberries and blackberries. During the harvest period, use netting to protect ripening fruits from hungry birds. After the fruit has been gathered, prune back fruiting canes and check near the soil line for signs of cane borers. Remove and discard any infested wood.

Flower Harvest

Many varieties of flowers, grasses and seed heads are ready to be harvested and preserved for crafts and indoor arrangements. As with herbs, the most popular preservation method is air drying, which works best for flowers like strawflower, yarrow and globe amaranth that contain relatively little moisture. Flowers with higher moisture content can be submerged in a granular desiccant compound, pressed between layers of absorbent paper, or preserved using a glycerin solution.

Harvest flowers just as they open, choosing unblemished specimens that feature graceful forms and growth habits. Strip off all leaves before tying and hanging flowers for air drying. Hydrangeas, especially “peegee” (Hydrangea paniculata), oakleaf (Hydrangea quercifolia), and mophead (Hydrangea macrophylla) types, may also be ready for August harvest. Choose flower panicles that have already begun to dry on the plant, with petal edges that are somewhat crisp to the touch. In the case of white-flowered peegee and oakleaf types, the flower panicles will have turned pink. Many mophead hydrangeas will display greenish petals.

Seed Harvest

Beginning in August, save seeds of heirloom or unusual varieties of edible and ornamental plants. Some seeds can be harvested “dry” by simply removing dried seed pods or receptacles from stems and shaking or blowing out seeds. Others, like tomato seeds, must be gathered “wet” and soaked in water, along with some attached plant material. During the soaking process, seeds tend to collect in the bottom of the soaking vessel, while other plant debris floats to the top. Wet-gathered seeds are then air dried. All seeds should be stored in cool, dry, dark conditions and labeled according to seed type and date of collection.

August marks the beginning of the harvest cycle that brings the growing season full circle. The month’s “to do” list may be long, but for most gardeners, the end result makes the labor worthwhile.

Growing Garden Gladiolus

Growing Garden Gladiolus Featured Image

Few gardeners feel ambivalent about common garden gladiolus (Gladiolus x hortulanus). In the decades since the first large-flowered hybrids were developed in the late 1830s, the tall flower spikes have been in and out of fashion many times. But glads and the gardeners who love them are nothing if not persistent. Even when horticultural fashion arbiters ignore the genus, the many-colored blooms show up in all kinds of places, from the end rows of vegetable gardens to carefully tended perennial borders and florists’ bouquets.

The tall garden hybrids are impressive, but the genus is full of other winning plants, including petite species and varieties that are well suited to container and small garden culture. Many species glads have an informal look that is more reminiscent of the wildflower garden than the florist shop. Some are also fragrant. All gladioli share the characteristic long, sword-shaped leaves and summer bloom time.

The following is a brief guide to some of the stars of the gladiolus galaxy.

Gladiolus Grandiflora Hybrids

These are the plants that come to mind when most people hear the word “gladiolus.” All grow from corms that are tender in cold winter climates. Standard grandifloras soar between 3 and 6 feet tall. The trumpet-shaped individual flowers, which can be up to 6 inches wide, open from the bottom of the spike to the top. Vendors carry scores of named varieties in just about every imaginable color. Bi-colored glads are available in an amazing array of combinations. Breeders have also developed shorter, dwarf varieties, including the vividly marked “butterfly” types, which reach only 1 to 3 feet.

Gladiolus Primulinus Hybrids

Primulinus Gladiolus
Primulinus Gladiolus

These plants, formerly known as Gladiolus primulinus, are now classified as Gladiolus dalenii. Somewhat shorter, at 2 to 4 feet tall, the individual blossoms are hooded, rather than open like the grandiflora types. They also tend to be smaller and less crowded on the stems, giving the plants an informal feel. The primulinus glads are especially useful to cold winter gardeners, because they are hardier than grandifloras. Some varieties, like golden-apricot ‘Boone,’ are cold hardy to USDA zone 6.

Gladiolus Nanus Hybrids

Nanus Gladiolus
Nanus Gladiolus

Also smaller and less formal than the grandifloras, the Nanus Hybrids, bred from Gladiolus nanus, bear up to three slim flower stalks with up to ten relatively small individual flowers. These cold-tolerant miniatures may also feature distinctive markings.

Byzantine Gladiolus

Gladiolus communis var. byzantinus
Gladiolus communis var. byzantinus

Native to the Mediterranean, Gladiolus communis var. byzantinus blooms somewhat earlier than grandiflora types and is also more cold-tolerant. The 24- to 36-inch stems are slender and arch gracefully, bearing ten to twelve individual, open magenta flowers per stem. Byzantine glads bloom earlier than their large-flowered relatives and naturalizes readily. They are fixtures in old southern gardens and have often been passed along from gardener to gardener.

Abyssinian Gladiolus

Abyssinian gladiolus

Formerly known as Acidanthera, Abyssinian gladiolus (Gladiolus callianthus ‘Murielae’) has a distinctive, orchid-like appearance and a pronounced fragrance. Introduced in the late nineteenth century, the blossoms feature sharply pointed white petals with dark purple centers. Abyssinian glads grow on slender stems that rise from 3 to 4 feet in height.

Growing Gladiolus

Gladiolus in basket tray
Dig tender gladiolus in fall and overwinter them in a cool, dry place.

Gladiolus corms should be planted 4 to 6 inches deep in rich, well-drained soil. Before planting, amend heavy clay soil with organic material like Fafard Garden Manure Blend or Fafard Natural and Organic Compost Blend. For container-grown specimens use a complete potting medium such as Fafard Ultra Potting Mix With Extended Feed. Tender gladiolus hybrids can be grown as annuals in cold weather climates. To keep desirable varieties from year to year, lift the corms in fall and store in a dry, frost-free location. Replant in spring after all danger of frost has passed. Grandiflora types may need stakes or other support to prevent the heavy flower stalks from flopping, but shorter varieties can stand on their own.

Gladioli are sometimes known as “sword lilies” for the sword-like shape of their foliage. Arm your beds and borders with these “swords” and they will cut through the summer garden doldrums.

10 Terrific Flowers for Honey Bees

Rudbeckia lacinata 'Autumn Sun'
Rudbeckia lacinata ‘Autumn Sun’ is a late-summer bloomer that bees love.

The decline in honey bees (Apis mellifera) has heightened the popularity of honey bee plants. Many favorite flowers for honey bees, like sweetclover, thistle, alfalfa and dandelion, are Eurasian plants too weedy for flower beds. Thankfully, there are some beautiful summer garden flowers, many being  North American natives, which are also great nectar and pollen plants favored by these Old World native bees. Regional natives are also superb forage plants for regional bees.
Fafard Premium Natural & Organic Compost Blend packThe best honey bee plants provide a good supply of both sugary nectar and protein-rich pollen sought after by these and other long-tongued bees. Lots of beautiful garden flowers provide both in high quantities. Here are our top 10 favorites organized by bloom time. Choose one for each blooming period and you’ll have great bee blooms throughout the growing season! All are sun-loving and grow best in good soils with regular to good drainage. Amend with Fafard Premium Natural & Organic Compost Blend and feed with a fertilizer for flowers, such as Black Gold Rose & Flower Fertilizer, for best results.

Early Summer Bee Flowers

Pale Purple Coneflower (Echinacea pallida, perennial)Pale Purple Coneflower (Echinacea pallida, perennial): An elegant beauty with fine, drooping petals, the pale purple coneflower is a bee favorite that also produces seeds much loved by finches. A native of grasslands and savannahs across the Eastern United States, this tough coneflower will bloom for up to three weeks from June to July. When in bloom, its flowers will feed lots of bees. You might even see a few butterflies on them as well.

Achillea millefolium 'Strawberry Seduction'Common yarrow (Achillea millefolium, perennial): The bright, flattened heads of common yarrow are covered with tiny daisy flowers that bees really favor. Native to both Eurasia and North America, this plant attracts loads of pollinators no matter where it’s planted. There are many beautiful varieties for the garden; two of the better variants are the rich red ‘Strawberry Seduction’ (image left) and ‘Wonderful Wampee’, which has pink flowers that fade to nearly white. 

Summer Bee Flowers

Sunflower with beesSunflowers (Helianthus annuus, annual): Nothing attracts and feeds bees like good old sunflowers. Their massive and prolific blooms come in shades of yellow, gold, red and orange and give way to lots of oil-rich seeds enjoyed by seed-eating birds and humans alike. There are literally hundreds of varieties to choose with various flower colors, heights and flower sizes. The dwarf varieties ‘Little Becka‘ (image left; 3-4’ tall with gold and brown flowers) and ‘Big Smile’ (1-2′ tall with classic golden flowers with black centers) are choice selections for any garden.
Agastache Blue BoaBlue Giant Hyssop (Agastache foeniculum, perennial): The pretty spires of purple flowers produced by the giant hyssop become simply covered with bees. A native across the northern regions of North America, this fragrant perennial in the mint family it tough and very hardy. The hybrid Agastache ‘Blue Boa’ (image left by Terra Nova Nurseries) is an exceptional variety from Terra Nova Nursery that is exceptionally beautiful.

Monarda punctata and Salvia coccineaHorsemint (Monarda punctata, perennial): Few garden perennials draw bees as efficiently as the long-blooming horsemint. A native of much of the United States, this sun-lover produces tiers of unique pink to white bracted flowers through much of summer and into fall. The blooms of these fragrant plants last a long time and become completely covered with pollinators. Plant in very well-drained soil for best performance.

Echinacea Dixie BellePurple Coneflower (Echinacea purpurea, perennial): The popularity of purple coneflowers and their many hybrids serves as a testament to their beauty and resilience. All are a favorite of bees, and like the pale purple coneflower, seed-eating birds enjoy the seedheads that follow. The purple-pink daisy flowers begin blooming in summer and will easily continue into late summer and even fall if the old flowers are removed. Some of the better new variants for big, long-blooming flowers include ‘Dixie Belle’ (left, image by Terra Nova Nurseries) and the super heavy blooming ‘Pica Bella’
Black-eyed SusanBlack-eyed Susan (Rudbeckia spp., annual or perennial): Nothing says summer like a beautiful black-eyed Susan, and bees appreciate their prolific flowers just as much as we do. One to seek out is the heavy blooming dwarf ‘Little Goldstar’ (Rudbeckia fulgida var. sullivantii ‘Little Goldstar’).
 

 Late-Summer and Fall Bee Flowers

Aster oblongifolius 'October Skies'Asters (Symphotrichum spp., perennial): The pinks, blues and purples of late-summer and fall aster flowers are a delight to all bees. There are so many wonderful varieties to choose from it’s hard to know where to start. The classic ‘October Skies’ (image left, Symphyotrichum oblongifolium ‘October Skies’) is a wonderful late bloomer with lavender-blue flowers and orange centers, and the dusty sky blue ‘Bluebird’  (Symphyotrichum laeve ‘Bluebird’) is an earlier bloomer with prolific flowers.

Eupatorium purpureumJoe-Pye Weeds (Eutrochium spp., perennial): This group of mid-to late-summer bloomers produces big, fuzzy heads of purplish-red flowers filled with nectar and pollen. Native across North America, many of the sun-loving perennials are adapted to moist ground. One of the finest garden varieties is Eutrochium purpureum ‘Little Red’ with its 4′ tall stature and pretty reddish-purple flowers.

SolidagoGoldenrods (Solidago spp., perennial): Lauded as one of the best bee flowers for late summer and fall, goldenrods become a buzzing mass when they open. In fact, goldenrod honey is a delicacy, known to be darker with a distinctive bite. Excellent garden-worthy goldenrods include the dwarf forms ‘Golden Fleece’ (Solidago sphacelata ‘Golden Fleece’) and ‘Baby Gold’ (Solidago ‘Baby Gold’).
With just a few of these garden beauties, feeding the bees all summer long is easy.

Top Flowering Vines for Garden Color

Vining gloriosa lily
The vining gloriosa lily has unique leaves with tendriled tips that allow it to ramble upwards.

Heavenly blue morning glories catching the first light of day, iridescent purple hyacinth beans hanging like summer jewels, delicate trumpets of the cardinal climber drawing hummingbirds in charms—these are just three of the finest vines for garden color. Each year we erect trellises and tall tipis just to grow our favorite climbing flowers. Summer just wouldn’t be summer without them.

The best flowering vines for our warm summer climate are tropical to subtropical. And even though they may not live through our cold winter, they are fast-growing, vigorous–able to reach tall heights by midsummer. Even better, they bloom and bloom and bloom offering flowers and ornamental pods in an array of bright, cheerful colors. Here are nine of the best vines to add vertical color and interest to any sunny summer garden:

Blue morning glory1. Morning Glory ‘Heavenly Blue’

The queen of the summer climbers is the heirloom ‘Heavenly Blue’ morning glory (Ipomoea tricolor ‘Heavenly Blue’). It’s large, funnel-shaped flowers of clear blue cover the vine from mid- to late-summer when many other flowers flag in the heat. (Ipomoea tricolor is native to the New World tropics, so humid heat is not a problem for this vine.) Towards fall, the flowers become even bluer and more prolific. The twining vines become thick and robust when happy, so provide plenty of room for this old-fashioned classic vine. A strong fence, trellis or pergola is recommended for support.

Purple-hued leaves and purple flowers and pods of hyacinth bean (Lablab purpureus)2. Hyacinth Bean

Space is required for this rambling, vigorous, flowering vine but the purple-hued leaves and purple flowers and pods of hyacinth bean (Lablab purpureus) make it a summer standout. Even in the hottest days of summer this African-native vine will shine. This bean is just for looks and not for eating. Be sure to give it a lot of space to twine and roam and feel free to gently prune it back as needed.

3. Black-Eyed Susan Vine

Pretty, dark-centered flowers of yellow, orange, white or peach dot the ever-beautiful black-eyed Susan vine (Thunbergia alata) when the weather is warm. The vines, though not as fast-growing as morning glories or hyacinth beans, become dense and lush when healthy and happy—offering lots of nice flowers that attract bees. The twining stems of this African native need a good trellis and out-of-bounds stems may need to be trimmed on occasion.

Creeping Gloxinia4. Creeping Gloxinia

Tolerance to partial sun makes creeping gloxinia (Asarina lophospermum) a good vine for patios and porches. Native to Mexico, its delicate, tubular flowers of white, russet red or pink, attract hummingbirds and rise from thin, twining stems lined with spade-shaped leaves with ragged, incised edges. This one is tame enough to plant in a large hanging basket or container. The popular selection Great Cascade™ Wine Red is very pretty.

5. Cardinal Climber

Hummingbirds cannot get enough of the hybrid cardinal climber’s (Ipomoea x sloteri) many tubular, red flowers produced along stems decorated with feathery leaves. The airy vine is deceptively delicate because its twining stems can reach up to 20’ by summer’s end. Expect it to be its most beautiful and flower-covered later in summer.

Spanish Flag6. Spanish Flag

The flowers of the Spanish flag (Ipomoea lobata) are like no other. Designed for hummingbirds, the flowers of this Brazilian vine are borne in one-sided clusters of pocketed blooms that are red in bud and open to palest yellow. The massive vines will completely cover a large trellis of the course of a summer, so plan big. The sunny flowers begin to appear in late summer and will continue until frost.

Malabar spinach7. Malabar Spinach

It’s attractive, heat-tolerant and edible, so what’s not to love? Malabar spinach (Basella alba) is a tropical vine native to tropical regions of Africa and Asia. Its thick twining purple-red stems and glossy leaves have a pleasing garden appeal, and they can be regularly harvested for eating. The flavor and texture of the leaves are spinach-like. Provide stout support for this twining vegetable. Inconspicuous flowers give way to berry-like black fruits that are subtly attractive.

8. Moonflower

Night bloomers like the moonflower (Ipomoea alba) use big size, white color and fragrance to attract moths in the fading hours of the evening. The enormous, funnel-shaped flowers are true novelties best enjoyed along a gazebo, pergola or a porch where they can best be viewed into the evening. The Mexican natives are quite heat tolerant and will bloom until frost.

9. Gloriosa Lily

The tender, tropical gloriosa lily (Gloriosa superba) is a true anomaly. It’s delicately twining stems and unique lives with tips that look and behave much like tendrils but its orange-red and yellow flowers look 100% lily. The tuberous roots can be stored in a cool place over winter but will not survive the harsh cold of northern winters. This native of Africa and Asia is a little less heat tolerant than some of the other vines we have mentioned. All parts of this plant are toxic, so it is not recommended for growing where children or pets might become attracted to the plants or flowers.
Summer vines appreciate good, friable soil that drains freely. Moderate to good fertility will do, so I recommend amending with Premium Natural & Organic Compost Blend before planting. Container-grown vines should be planted in Fafard Ultra Outdoor Planting Mix. All of these vines will appreciate a little food for garden flowers upon planting as well.

Corydalis: A Charming Spring Shade Perennial

Corydalis malkensis
Large swan-white blooms grace the cheerful Corydalis malkensis.

Endearing little sprites that carry flocks of dainty, spurred blooms above clumps of ferny divided leaves, tuberous Corydalis (crested larks) are among the most valuable early-spring “bulbs” for shade. These low-growing perennials have long been known to horticulture: the most familiar of the tribe, Corydalis solida, has been kicking around gardens since at least the sixteenth century. But in the last few decades, a multi-hued array of new species and cultivars has entered cultivation, taking the genus into exciting new territory.

Spring Corydalis

The genus Corydalis also has a non-tuberous side, comprising several dozen perennials or annuals that grow from fibrous roots (rather than from swollen underground stems) and that remain in leaf all season (rather than disappearing shortly after bloom). These fibrous-rooted corydali include several species that are well worth a place in the ornamental garden – among them Corydalis lutea (now Pseudofumaria lutea), known for its profusion of yellow blooms and self-sown seedlings; and Corydalis flexuosa, whose luminous blue flowers and notorious heat intolerance have caused much lusting and despair among eastern North American plant enthusiasts. None of them, however, blooms in in early spring in hues ranging from blue to purple to bright red to pale yellow to white. For that, you’ll need Corydalis with tubers – especially Corydalis solida.

Corydalis ornata
Delicate blue flowers grace Corydalis ornata in spring.

Native to woodlands from southern Scandinavia to northern Spain to the Ural Mountains to northern Greece, Corydalis solida assumes a dizzying variety of colors and forms across its vast natural range. Until relatively recently, gardeners had to settle for the most common, rather nondescript purple-flowered forms. No longer. A wealth of cultivars in a broad and tantalizing range of hues now populate the pages of bulb catalogs. Among the oldest and most renowned of these new-wave corydali is the brick-red ‘George Baker’, one of a pack of red- and pink-flowered selections hailing from the mountains of Transylvania. (Caveat emptor – bargain-priced tubers sold under Mr. Baker’s name are often imposter seedlings bearing dingy-red blooms.) Other outstanding cultivars from the sunset side of the Corydalis solida color range include deep rose-red ‘Cantata’, rich lilac-pink ‘Sixtus’, and soft creamy-pink ‘Blushing Girl’. At the violet end of the spectrum are pale-lilac ‘Ballade’, denim-blue ‘Compact’, icy bluish-white ‘Evening Dream’, and the aptly named ‘Purple Beauty’. Milky-flowered ‘Snowstorm’ and the floriferous, late-blooming ‘White Knight’ are among the best white-flowered selections.

Corydalis solida 'George Baker'
The bright red flowers of Corydalis solida ‘George Baker’ are a real standout.

Most Corydalis solida cultivars readily self-sow (with the assistance of seed-dispersing ants), their seedlings often reverting to the muddy purple floral tones of the wild species. Remove such seedlings to keep them from crowding out their more colorful parents.
The world awaits a yellow-flowered Corydalis solida (reputedly such forms exist in the wild). Crosses with the sulfur-bloomed Siberian native Corydalis bracteata sometimes occur, however, their offspring (known horticulturally as Corydalis × allenii) producing pale creamy-yellow, lilac-brushed blooms and fetching, deeply cleft leaves. Corydalis bracteata and its fellow Siberian Corydalis gracilis also make excellent yellow-flowered garden subjects for areas that have long, cold, snow-locked winters.
Woodland Corydalis are habit-forming. Once you’ve discovered Corydalis solida and its hybrids, you’ll want to have a go at the many other garden-worthy species – perhaps Corydalis malkensis, with its voluptuous, gaping, swan-white blooms; or Corydalis kusnetzovii, which flowers in a beguiling shades of pale pink; or one of the brilliant-blue-flowered East Asian species (such as Corydalis ornata and Corydalis turtschaninovii). All thrive in partial shade and humus-rich soil; amend sandy or heavy soils with a good compost such as Fafard Premium Organic Compost or Fafard Canadian Sphagnum Peat Moss.
Real corydalis addicts will also want to explore some of the Central Asian species, which are typified by pink or white, chocolate-nosed flowers, blue-green foliage, and a preference for sunny, gritty-soiled niches that stay relatively dry in summer (such as a rock garden or trough). As with the woodland Corydalis, they present a wealth of delightful possibilities for the early spring garden.

Easy Spring Container Gardening

Simple pots of colorful annuals
Simple pots of colorful annuals can be placed in the spring garden to add color and interest.

Bountiful spring containers are a joyous way to reign in the new season. Nothing welcomes spring better than exquisitely orchestrated collections of potted flowers. The key is choosing suites of plants and pots that are seasonal and complimentary—whether the compositions are simple or flamboyant.

Some gardeners take their spring container gardening very seriously—planting up bulb and perennial pots in fall for spring show. But, this practice can be problematic, if gardeners don’t take care.  Tulip bulbs in pots are highly vulnerable to rodent attack, and some bulbs or perennials may not survive hard winters or can heave in pots. Both potential problems call for protective pot covers and storage of containers in protected spots in a cold garage or in a protected spot beside the house. Or pre-planting can be bypassed entirely. As more and more potted bulbs are offered at spring planting time, fall container prep is no longer a prerequisite.

Choosing Containers

When designing spring container plantings, start by choosing the pots. Pretty glazed pots in subdued earthy or mossy tones create a pleasing base for brightly colored flowers. Pots of different complimentary shapes and sizes look the nicest when arranged in groups. For symmetrical groupings choose an even number of pots, and for asymmetrical groupings choose an odd number. Once pots are chosen, artfully place them together, considering height and shape.

Choosing Container Mix

Next, choose your container mix. Fafard Ultra Container Mix or Fafard Ultra Potting Mix with Extended Feed are great choices for potted outdoor plantings. Not only does it feed plants for up to six months, but it contains moisture-holding crystals that reduce the need to water as often.

Choosing Container Plants

Finally, establish your color pallet and choose your plants—considering height and texture as well as bloom time. More often than not, bright, gregarious colors are what people like to plant in spring (enough with dreary subdued landscapes), but pastels are also popular. Cheerful combinations of yellow, orange, red, pink and blue flowers make spring container gardens pop.
Past plant combinations that have worked well for me include mixes of hardworking annuals, such as pansies, violas, stocks, trailing lobelia and twinspur (Diascia spp.), in addition to choice perennials like colorful golden bleeding heart (Dicentra spectabilis ‘Gold Heart’), Heuchera, and any bulbs that I can get my hands on. Less common perennials, like Tradescantia ‘Sweet Kate’ or trailing bellflower (Campanula poscharskyana), also add polish and oomph to containers. Even miniature roses can be added for color and flair.

Planting Containers

Before planting up my containers, I fill the pots ¾ full with potting mix to allow space to arrange my planting before bedding them in. This step is essential to visually balance the plantings and can make the difference between your plantings looking like a hodgepodge or a well-planned container garden. Cascading plants always look best along the edge of the pot while upright plants should be centered. During this process I also consider how different potted plantings will complement one another. Once my design is set, it’s time to start planting.
When transplanting bulbs, be sure to move them without allowing the rootball to lose its shape; then firmly press the soil down around the roots to keep the foliage and flowers tidy and upright. Perennials and annuals are often “pot bound”, meaning their roots have become densely intertwined. Before planting, gently tease apart tightly bound roots a bit to loosen them. Then, sprinkle the pots with a little slow-release fertilizer. Finally, irrigate the pots until the water flows out of the drainage holes.
It’s a joy to watch spring container creations fill in and burst forth. Once bulb flowers are spent, be sure to cut the old stems back to keep pots looking clean and pretty. Then as summer approaches, move out the flagging cool-season plants and replace them with vibrant warm-season ornamentals that will shine until fall.

Indoor Bloomers for Midwinter Cheer

Streptocarpus 'Party Pinafore'
Streptocarpus ‘Party Pinafore’

Most of us in the Frozen North could really use a hit of spring about now. How about flowers, for instance? Or better yet, how about a lush plant in full bloom, providing a colorful (and therapeutic) dose of midwinter cheer?
That won’t be happening in most of our gardens for a few weeks yet (although here in southern New England the early witch-hazels often open their spidery blooms before February is out). On the other hand, any number of plants will provide a bevy of winter blooms in a sun room or kitchen or any suitable indoor space, given a modest investment of care. Furthermore, some of them double their display with equally showy foliage.

Purple-leaved Oxalis

One sure sign of spring’s approach is the mass arrival of purple-leaved oxalis (Oxalis triangularis) in supermarkets and department stores, in anticipation of St. Patrick’s Day. This handsome and easy-to-grow perennial is much more than a one-holiday wonder, however. Although the deep-maroon, three-lobed, shamrock-like leaves give it obvious St. Patty’s Day caché, they are perhaps even more appealing in winter, especially when punctuated with the pale pink, funnel-shaped flowers that this South American native produces year-round. Plants can also be purchased as “bulbs”, which are actually scaly, caterpillar-like underground stems (rhizomes) that should be planted horizontally an inch or two below the soil surface in Fafard® Professional Potting Mix. Full to partial sun, almost any potting mix, and anything but total neglect will keep this tough perennial happy. It is also remarkably cold-hardy, functioning well as a foliage accent in mixed borders and other perennial plantings from Washington DC into the South.

Calathea 'Holiday'
Calathea ‘Holiday’

Calatheas

Calatheas, like purple-leaved oxalis, are typically known and grown for their showy foliage. Yet, a few surprise us with blossoms that stand clear of the foliage in an arresting and anything-but-drab display – rather than cowering blandly near the bases of the leaves. Among the best of these showy-flowered peacock plants are a series of hybrids developed in Indonesia in the early 2000s. And none is better than the cultivar ‘Holiday’, whose striking blooms – with rose-pink, pale-eyed petals tipped with olive-green – open sporadically throughout the year. When not in flower, ‘Holiday’ provides ample ornament with its broadly oval, bright green leaves marked by purple-black chevrons and silvery, purple-edged margins. Other ever-blooming calathea hybrids include ‘Constellation’, ‘Jungle Cat’, ‘Maria’, and ‘Royal Standard.’ (Their flowery parent, Calathea loeseneri, also makes a wonderful subject for a shady indoor nook.) All calatheas prosper in full to partial shade, warm humid conditions (although they’ll tolerate less), and a coarse humus-rich potting medium. Fafard African Violet Potting Mix is a good fit. Repot and divide plants yearly or once every two years.

Cymbidium orchids
Cymbidium orchids grow beautifully in the cool winter months.

Orchids

Terrestrial to semi-terrestrial orchids of many types bloom beautifully in the winter months. Most notably are Cymbidium, Paphiopedilum, and Phaius species, grexes, and cultivars. All provide bright, long-lasting floral color and thrive in Fafard’s Premium Orchid Mix, which offers a perfect blend of fir bark, chopped coir and perlite. 

Spiral Ginger

For sheer nonstop flower power and ease of care, few plants can match spiral ginger (Chamaecostus cuspidatus, formerly Costus cuspidatus). The golden-orange, ruffle-edged, blooms look almost orchid-like and appear year-round on cane-like, 2-foot-tall stems clothed with glossy, dark-green, broadly lance-shaped leaves. Flowering is most abundant in summer, but blooms continue to open throughout fall and winter, particularly in warm humid niches. Give it bright shade, a fertile compost-rich growing medium, such as Fafard® Organic Potting Mix, and moderate watering for maximum display. Other members of the costus tribe, like dwarf cone ginger (Costus woodsonii) and crepe ginger (Cheilocostus speciosus), thrive in similar conditions, and are also well worth seeking out.

Oxalis triangularis 'Francis'

Streptocarpus

No discussion of winter-blooming (and ever-blooming) houseplants would be complete without mention of cape primroses. Members of the southern African genus Streptocarpus, and close relatives of African violets, these little evergreen perennials perch easily on a modest windowsill (fitting happily in a 4-inch pot), where they bloom their heads off year-round, the funnel-shaped flowers smiling from atop wiry, 4- to 8-inch stems. Hybrids abound in all manner of luscious exotic colors and patterns, with the flowers’ two rounded, ear-like upper lobes typically differing in hue from the three lower ones, and their throats often bearing dramatic contrasting streaks. Partial shade, Fafard African Violet Potting Mix, mild humid summers, and coolish somewhat drier winters will result in nearly constant blooms, and loads of midwinter cheer.
