  1. Small Native Shrubs with Big Fall Color

    A compact cranberry viburnum glows like embers in an autumn landscape.

    Some of the most brilliant fall shrubs come in small packages and have the added benefit of being native. This sets them apart from the many non-native, ecological troublemakers sold in most garden centers, which are seasonally beautiful but noxiously invasive. Landscape favorites like dwarf Burning bush (Euonymus alatus) and Japanese barberry (Berberis thunbergii), are among the worst weedy offenders.

  2. Tall Sedums for Fall Gardens

    DisplayImage.ashx

    Sedum ‘Autumn Fire’ mingles with a well-designed mix of textural perennials and shrubs.

    Tall sedums (Sedum spectabile hybrids) look pretty through much of the year—aside from late winter and spring, before they have broken bud. Through summer they provide mounds of lush, blue-green foliage, and in early winter their dried flower heads hold up moderately well before being flattened by snow, but late summer and fall are when they shine the most. Their sturdy stems support mounds of rosy pink blooms that glow in the late-season sun. New varieties make growing and designing with these tried-and-true perennials even more gratifying and fun.

    Bold Tall Sedums & Planting Combos

    Tall sedums have broken the mold of the old-fashioned dusky pink ‘Autumn Joy’ of your grandmother’s garden. Extra bright flowers and unique foliage colors, like bronze, purple and near-black, mark some of the newer tall sedum varieties.  Some are extra tall and others are very compact and more densely flowered.

    Sedum ‘Thunderhead’

    Take the ‘Thunderhead’ introduction by Terra Nova Nurseries; its giant, bright, rose-red flower heads stand on strong, 18” stems above bronzy green foliage. For a great planting combo, plant it in swaths alongside soft, mounding, blue-green ‘Blue Zinger’ sedge and bright-yellow flowered Helianthus ‘Low Down’, which only grows to 2-feet high.

    Sedum ‘Dark Magic’

    One for outstanding foliage as well as flowers is the 2015 introduction ‘Dark Magic’, which has deepest burgundy foliage all season and large heads of burgundy pink flowers in late-summer and fall. The compact plants only reach 12” high, making this a great plant for border edges. Its upright habit makes it the perfect complement to lower, more mounded grasses and perennials. Try evergreen, lavender-flowered germander (Teucrium chamaedrys) or tidy thyme (Thymus spp.) plants.

    Sedum ‘Crystal Pink’

    In contrast, the super compact ‘Crystal Pink’ becomes literally covered with palest green and pink flowers. Plants reach no more than one foot and their light flowers complement taller, darker-colored garden plants.

    Sedum ‘Frosty Morn’ and ‘Autumn Delight’

    Frosty Morn

    Variegated leaves add to the visual appeal of ‘Frosty Morn’

    Another bright sedum is the cool ‘Frosty Morn’. This variegated counterpart to ‘Autumn Joy’ is surprisingly vigorous. Its bright mounds of foliage complement darker-leaved plants and are best planted in clumps of five to seven plants to show off the silvery effect of the ivory-edged leaves. Late in the season, they become topped with subtle, dusty pink flowers. The darker flowered ‘Autumn Delight’ is a bolder variegated form with deeper variegated leaves and bright rose flowers.

    The deep rose flowers of ‘Autumn Delight’ look lovely against its variegated leaves.

    Sedum ‘Autumn Fire’

    Gardeners looking for classic tall sedum looks but more exciting flowers might consider ‘Autumn Fire’. Tall plants produce large, flattened clusters of rose-pink flowers that are to a darker, richer hue. The plants themselves have significant presence in the landscape with their dense stems that reach 2 to 3 feet high.

    Growing Tall Sedums

    Bees and butterflies are attracted to tall sedum flowers.

    Like all sedums, these plants prefer drier feet, but they aren’t as drought tolerant as some of the short, spreading Sedum species able to withstand really high heat and drought. Plant tall sedums in porous, mineral-rich soil with added organic matter. Raised bed spaces can be amended with Fafard Premium Natural & Organic Compost for perfect rooting.

    All sedums attract bees and butterflies,  making them perfect for pollinator gardens. After fall flowering, the seedheads should be left until they are no longer ornamental. Cut them back on a dry midwinter’s day, and wait until the soils warm in spring and their rosettes of fleshy leaves begin to grow again.

  3. Top 10 Tough Fast-Growing Shade Trees

    Red maples are very fast growing and spectacular in fall.

    What makes a fast-growing shade tree exceptional? First, it must be strong-wooded and long lived. Second, it must be attractive, providing desirable seasonal characteristics to make your yard look great. Those that are native, disease resistant, and well-adapted to a given region are also optimal. Finally, they should have minimal messy fruits to reduce the hassle of seasonal clean up.

  5. The Prettiest Garden Lavenders

    Sweeps of hedge lavender add color and fragrance to a patio garden.

    Wands of fragrant purple blooms dance in the wind, feeding bees, and shining cheerfully on even the hottest summer days. These are the flowers of lavender, a plant beloved for its aroma and ability to grow well in tough Mediterranean climates. This aromatic evergreen perennial has been used in perfumes, poultices and potpourris for centuries, giving it high value in the herb garden. And, many diverse varieties exist, so there’s lavender to satisfy almost every gardener.

    Nothing is prettier than a field of red, windblown poppies. The delicate blooms rise from slender stems, and their colorful petals resemble crushed tissue paper—giving these classic garden flowers lasting appeal. Poppies are diverse, and can be grown in practically any garden. Some are long-lived perennials while others are fleeting annuals the bloom spectacularly for a short time before setting seed.

  8. Two Butterfly Garden Designs

    A monarch butterfly feeds on swamp milkweed.

    Everyone loves butterflies, and the threat to monarch populations has spurred increased interest in butterfly gardening. When planning a smart butterfly garden, you want to include plants that feed both adult butterflies and their caterpillars. This is essential because butterfly caterpillars are species specific, meaning they only feed on specific plants.

    Color, design, and site conditions are important when creating butterfly gardens. To make the job easy for new pollinator gardeners, we created two designs that are colorful and appeal to black swallowtail and monarch butterflies. Most butterfly plants are sun-loving, so these gardens are all adapted to sunny garden spaces.

    Black Swallowtail Garden Plants

    The caterpillars of black swallowtail butterflies feed on many plants in the carrot family, Apiaceae. These eastern North American butterflies have many native host plants, but none are attractive enough for ornamental gardening. Thankfully, quite a few cultivated flowers also feed them. These include bronze fennel, Queen Anne’s lace, lace flower, and dill. When mixed with colorful, compact Magellan zinnias and Sonata coreopsis, which feed adult butterflies, a wild, lacy flower garden is created.

    Black Swallowtail Garden Design: This simple design shows a traditional rectangular flower border, but it can be adapted to fit any garden shape. Just be sure to keep the taller plants towards the center or back of the border. Most of these flowers are annuals, meaning they need to be planted year after year.

    Monarch Garden Plants

    Monarch caterpillars only feed on milkweed plants.

    All milkweed species (Asclepias spp.) feed monarchs. These colorful perennials contain protective chemicals that the caterpillars feed on, which render both the caterpillars and adult butterflies unpalatable to birds. The prettiest of all milkweeds include the orange-flowered butterflyweed (Asclepias tuberosa (USDA Hardiness Zones 4-9)), pink-flowered swamp milkweed (Asclepias incarnata (USDA Hardiness Zones 3-9), and orange-red flowered Mexican milkweed (Asclepias curassavica (USDA Hardiness Zones 8-10)), which self sows yearly. Monarch adults feed on all manner of butterfly flowers. The best are fall-flowering species that support the butterflies as they head to Mexico late in the season, like goldenrod and asters. [Click here to read more about growing milkweeds for monarchs.]

    Monarch Garden Design: This border design includes three showy milkweed species and dwarf late-season asters (such as Symphyotrichum novi-belgii ‘Lady-in-Blue’ (12-inches tall) or ‘Nesthäkchen’ (18-inches tall) and dwarf goldenrod (such as Solidago ‘Golden Baby’ (18-inches tall) or ‘Little Lemon’ (18-inches tall)) to feed migrating monarchs.

    Planting your Butterfly Garden

    These gardens are all designed for full-sun exposures. When planting them, feed the soil with Fafard Premium Natural & Organic Compost to ensure the plants get a good start. You might also consider feeding them with a good flower fertilizer approved for organic gardening. Another important note is to avoid using insecticides, which will damage or kill visiting butterflies.

    These simple gardens are pretty and sure to lure lots of beautiful butterflies to your yard. To learn more about pollinator conservation and gardening, visit the Xerces Society’s Pollinator Conservation page.

  9. Favorite Heirloom Garden Flowers from Seed

    Heirloom garden flowers are perfect for informal cottage gardens.

    Imagine a sweeping cottage garden of China pinks, petunias, and marigolds interspersed with a tangle of colorful sweet peas and lacy love-in-a-mist. Old fashioned flowers such as these remain in vogue for the same reason our grandmothers grew them. They are lovely, easily grown from seed, and their seeds can be collected from year to year—making them perfect for gardeners on a budget.

    Choice heirloom flowers are brightly colored, long-blooming, and easy to manage. Quite a few have the added bonus of being highly fragrant, because fragrance was considered an important floral trait from Victorian times to the mid-nineteenth century.

    The majority of these flowers are best started indoors from seed at the beginning of the growing season, but several can be started outdoors. Our favorites will be sure to add value to your flower garden and containers this season.

    Top 10 Heirloom Flowers from Seed

    China pinks (Dianthus chinensis)

    These highly fragrant, short-lived perennials thrive where summers are cool and have frilly blooms in shades of red, white, and pink. Most reach a foot in height and are perfect for sunny border edges. Try the lovely Single Flowered Mix from Select seeds with single flowers in mixed colors. Start seeds indoors in February or March. 

    Heliotrope (Heliotropium arborescens)

    These bushy, sun-loving bedding plants reach 2 to 3 feet and develop broad clusters of small, sweetly fragrant purple, lavender, or white flowers that attract butterflies. Remove old flower heads for repeat bloom all season. The very old variety ‘Amaretto‘ has pale violet flowers that smell of almonds. Start these from seed indoors in February.

     

    Sweet Pea (Lathyrus odoratus)

    Sweet peas are some of the most fragrant cool-season flowers. The delicate, tendriled vines require light trellising. Long-stemmed clusters of sweet-smelling flowers appear by late spring and are perfect for cutting. The antique ‘Perfume Delight’ is especially fragrant and more heat tolerant than most. Start sweet peas indoors from seed in February or March.

     

    Sweet Alyssum (Lobularia maritima)

    The ever-blooming nature of this small, fragrant garden annual has made it one of the best for border and container edges. It blooms well in both hot and cool weather with clusters of tiny white, pink, or purple flowers. Try the honey-scented Gulf Winds mix from Renee’s Garden Seeds, which has flowers of light pink, rose, lilac, and white. The seeds are very fine, so be sure not to accidentally plant too many when starting them indoors. Start these no later than March.

    Marigolds (Tagetes hybrids)

    Loads of warm-hued heirloom marigolds are still available to brighten contemporary flower beds. These tough sun lovers shine through the most difficult summers, keeping gardens looking good through the swelter. For garden edges, choose the 1903 heirloom French Marigold ‘Legion of Honor’. Its fragrant flowers are dark orange with gold edges. Small-flowered signet marigolds are also uncommonly showy with their ferny foliage and bushy habits. Plant seeds in March for late-May planting.

    Jasmine-Scented Tobacco (Nicotiana alata)

    The white blooms of jasmine-scented tobacco are most fragrant at night and pollinated by moths. The tubular flowers appear on plants reaching 3 to 4 feet high. This heat tolerant annual will tolerate some shade and will bloom well into fall. High Mowing Organic Seeds sells seeds for this old-fashioned beauty. Cut back the old flower stalks to encourage flowering. Start the seeds indoors no later than March. (Image by Carl E. Lewis)

    Love-in-a-Mist (Nigella damascena)

    Unusual lacy flowers make love-in-a-mist especially charming in the garden. The flowers may be violet-blue, purple, white, or pink. Once they have finished flowering, their dry seed pods are also visually interesting and useful in dried arrangements. They do tend to self-sow, so expect lots of seedlings to appear the following season. They flower best in cool weather and are short-lived, so they can be started both in early spring and late summer for two seasons of bloom.

    Old-Fashioned Petunia (Petunia hybrid)

    Heirloom petunias tend have looser habits that require regular pruning, but they are also charming and free-flowering. One of the most unique of the seed-grown heirlooms is ‘Old-Fashioned Climbing‘. This pretty rambler has highly fragrant flowers in shades of purple, lavender, and white that bloom above the foliage. Start the seeds no later than March for summer enjoyment.

    Scarlet Sage (Salvia spendens)

    Older varieties of scarlet sage are taller and bushier but no less free flowering. The tall and elegant ‘Van Houttei’ is one of the earliest cultivated forms. The bushy 3- to 4-foot variety thrives in heat and becomes covered with spikes of deep red blooms that attract the hummingbirds. Pinch back spent flowering stems to encourage more flowers! Start the seeds in February or March.

     

    Growing Heirlooms from Seed

    Some heirlooms, such as love-in-a-mist, can be directly sown in the ground outdoors, but most are best started indoors. Start your seeds in seed trays fitted with six-pack flats, which give growing flowers enough space for root and shoot growth. Fill the flats with premium OMRI Listed Black Gold Seedling Mix, which holds moisture and drains well.  Moisten the mix before planting for easier watering after planting. If planting your new seedlings in containers, choose Fafard Ultra Container Mix with Extended Feed, which feeds flowers for up to 6 months.

    Follow seed packet instructions for planting guidelines and expected germination times. Smaller seeds usually need to be lightly covered with mix while larger seeds require deeper planting. Plant each cell with two to three seeds to make sure you get at least one seedling per cell. You only want one seedling per cell, so pinch out the weakest seedlings that germinate and leave the largest. Seeds often sprout best in temperatures between 68-73º F. Warm-season annuals germinate faster if flats are placed on heat mats.

    Good light is important for strong growth. You can either start your seeds in a sunny, south-facing window of beneath strip shop lights fitted with broad-spectrum bulbs. One shop light will supply light to two trays. Keep trays 4 inches from the grow lights to keep seedlings from getting leggy. Raise the lights as your plants grow. Once seedlings develop new leaves, feed them with half-strength Proven Winners Premium Water Soluble Plant Food.

    Before planting your tender heirloom flower starts outdoors, acclimate them to the natural sunlight and wind by placing them in a protected spot with partial sun for one week. This process of “hardening off” allows indoor-grown starts to toughen up before outdoor planting. After this step, they will be ready to plant in your garden or containers.

  10. Traditional Asian Vegetables for the Garden

    Asparagus bean

    Many prized vegetables originate from or were bred in Asian countries, from India to Japan to Malaysia. Great emphasis is placed on the beans, cucurbits, greens, and root vegetables, and many are very old, select varieties collected and grown for generations. The best are flavorful and great for any home garden.

    Local climate often dictates growth preference. For example, vegetables bred in Thailand, Vietnam, or Malaysia are heat and drought tolerant, while the vegetables of northern China prefer cooler climates. Many of these crops are unknown to American gardeners, but consider trying a few this season, if you like Asian cuisine or simply delicious garden-fresh food.

    Beans

    Yardlong bean

    The asparagus or winged bean (Psophocarpus tetragonolobus) is both attractive and delicious—sporting red flowers and beautiful winged beans.  It is a warm season crop that produces long twining vines that produce edible beans just 75 days after planting. It is grown in tropical regions due to its marked tolerance to high heat. The unusual looking pods taste like a cross between peas and asparagus. Asparagus bean has added value because the leaves are eaten like spinach, and the edible roots have a nutty flavor.

    Also well-adapted to high heat and summer growing is the yardlong bean (Vigna unguiculata ssp. sesquipedalis). Its vigorous vines bear loads of very long beans that reach 12- to 16-inches and taste delicious. They have been grown for centuries in China and are best sautéed or stir fried.

    Cucurbits

    Angled luffa

    Japanese cucumbers are unique in that they are very long, thin skinned, and crisp. They grow on rambling vines that are best trellised to accommodate the cucumbers that can reach between 8 to 12 inches. Try the open-pollinated variety ‘Sooyow Nishiki’, which has thin, warty skin and crisp, sweet flesh.

    Many Asian melons exist, which are bred and selected to be remarkable sweet. The open-pollinated Japanese variety, ‘New Melon’ is golden, smooth skinned, and was developed in the 1950s for Japanese growers. Each vigorous vine produces between four to eight melons. Be sure to plant them as early as possible, because vines take between 110 to 120 days to produce fruit.

    Asian melons

    Most westerners know luffa as a natural sponge for bathing, but in China the young gourds are a popular vegetable. The angled luffa (Luffa acutangula) is commonly referred to as Chinese okra and has a sweet taste (much like zucchini) when harvested young. Give the vines plenty of space, or trellis them for easier growing and harvest.

    Greens & Cabbages

    Chinese cabbage

    Bok choy (pak choi) is a mild, cool-season green that produces rosettes of green leaves with fleshy white bases. These are fast-growing and typically eaten stir fried. Some varieties are very small and others large. The super small variety ‘Extra Dwarf Pak Choi’ is very fast growing , reaching full size in just 30 days, and is just right for edible container gardening.

    Valued as a spring vegetable across Asia, Korean minari is a leafy green that tastes much like watercress. It is closely related to celery and is a vital ingredient in Korean bibimbap bowls or can be prepared as a spicy vegetable side dish. It grows best in cool weather and slows growth in temperatures above 70 degrees F.

    Chinese cabbage is a well-known, cool-season crop that produces large heads that may be barrel-shaped or loose headed. Try the old Japanese variety, ‘Aichi’, which is a large, barrel-shaped variety that produces dense heads with a sweet cabbagy flavor. These grow and taste best in the mild temperatures of spring or fall.

    Root Vegetables

    Watermelon radish

    Radishes play an important role in the cuisine of many Asian cultures. These include watermelon, daikon, and hot radishes as well as those used for microgreens. All radishes are fast growing and best suited to growing in cool weather. When temperatures are hot, they don’t develop substantial roots and taste very hot. Watermelon radish types are some of the most beautiful with their red interiors and greenish-white exteriors. They are also fun for kids to grow. Try the Chinese radish ‘Red Meat’, which is thin skinned, sweet, and ready to harvest 60 days after planting.

    Turnips are a common root vegetable, but most western gardeners are not familiar with red turnips. These fast-growing, sweet root vegetables are popular in Asia and eaten fresh or cooked. They are typically red on the outside and white or pinkish on the inside. Try the traditional Japanese turnip ‘Hidabeni‘, which has flattened roots with scarlet exteriors and white interiors.

    Eggplant

    Green Japanese eggplant

    Eggplant is essential to Asian cuisine, from India to Japan. Most are elongated, mild, thin-skinned, and have few seeds. This warm-season crop bears many fruits over the season. One of the easiest and best varieties to try is the Taiwanese eggplant ‘Ping Tung Long‘, which is very heat tolerant and has bright purple fruits that reach over a foot long. The equally large green fruits of the Japanese ‘Choryoku‘ are also firm, sweet, and delicious.

    Favorite Thai eggplants are a bit different in that many are smaller and oval or round. They may be green striped or deep purple. The small, round variety ‘Petch Siam’ is grown from India to Vietnam. Its small green striped fruits are numerous, and the plants like high heat.

    Squash

    Kabocha squash

    There are many squash grown and favored across Asian countries, but some of the sweetest and best tasting are kabocha winter squash. These somewhat flattened, globe-shaped squash typically have dark green skin and gold to orange flesh that is smooth and very sweet. The open-pollinated kabocha from Japan, ‘Kuri Winter’, has very sweet, thick, golden flesh and dark blue-green skin. Plant it early as vines take 95 to 110 days to produce good fruit.

    Vegetable Care

    For high vegetable yields be sure to feed your crops with a granular organic vegetable fertilizer early in the season. Amendments such as Fafard Premium Natural & Organic Compost and Fafard Garden Manure Blend also ensure high soil moisture and aeration to encourage vigorous root growth. Double–digging is another great way to optimize deep root growth to help plants withstand moderate drought and high heat.
