Monarch Host and Nectar Source
Asclepias Soulmate features nectar laden, rose-pink flowers with white centers and vanilla-scented blooms. This U.S. native serves as both a nectar source and host plant for Monarchs, while also attracting hummingbirds and various other pollinators. Its slender seed pods burst open in fall, releasing silky-threaded seeds that float on the breeze. Though late to emerge in spring, this low-maintenance plant provides four-season interest and establishes easily in gardens.

Botanical Name

Asclepias incarnata 'Soulmate'

Asclepias General Information

Asclepias incarnata is a native North American perennial commonly found in swamps, river bottomlands and wet meadows. Its foliage serves as a crucial host for Monarch butterflies, providing food for their caterpillars, while its nectar is a food source for hummingbirds, butterflies and many other pollinators. The plant also attracts various native bees and honeybees, making it an excellent addition to any pollinator garden. Stems exude a milky sap when cut. Whether massing plants in large drifts or as a single accent, Asclepias is one of our showiest native wildflowers.

Asclepias Plant Care

Plant in full sun to partial shade in moist, well-draining soil. It tolerates average or clay garden soil and naturally thrives in wet areas. Can be slow to establish but is long-lived once it takes hold. Late to emerge in the spring. Cut back stems to about 6 inches above ground in late fall or early spring before new growth appears. Avoid disturbing the roots once established, as plants develop deep taproots. Though generally pest-resistant, watch for aphids and treat with a strong water spray if needed. The plant's milky sap makes it naturally deer resistant. Remove spent flowers to encourage rebloom and prevent self sowing (if desired). Allow some spent flowers from 2nd bloom to remain on plant to form ornamental fruit for late season interest.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
