Two Butterfly Garden Designs
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
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.

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.
