Monarch Host and Nectar Source
A choice perennial to attract butterflies! Soulmate status abounds as nectar-laden, rose-pink flowers with white-starred centers attract butterflies - plus, its foliage will cradle Monarch eggs/caterpillars. Vanilla-scented flowers emerge in attractive branching clusters. As quoted by George Carlin; “The caterpillar does all the work, but the butterfly gets all the publicity.” This U.S. native perennial will ensure a reliable food source for butterflies. The slender seed pods of Asclepias Soulmate in late summer throughout winter provide four-season appeal. The pods, usually in pairs, burst open in fall to reveal brown seeds on silky threads that hitch a ride with the breeze like glistening parachutes. Plants will emerge late in the spring but require little care once established. Asclepias incarnata also attracts hummingbirds, hummingbird moths, bumblebees, honeybees, and a variety of butterflies: eastern tiger swallowtails, buckeyes, fritillaries, hairstreaks, and spicebush swallowtails.

Botanical Name

Asclepias incarnata 'Soulmate'

Asclepias General Information

Asclepias are best in sunny locations with sandy soils. Milkweed is a nectar source for Monarch butterflies and also a host plant for them to lay their eggs. Plant in groups to attract more butterflies.

Asclepias Plant Care

Low maintenance. Self-sows readily. Can be slow to establish but is long-lived once it takes hold. Late to emerge in the spring. Divide and cut back in spring when new growth starts, being careful of long taproot. Long taproot makes division difficult. Be aware that Asclepias is slow to recover once moved or divided. Remove spent flowers to encourage rebloom and prevent self sowing. 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!
