Long Blooming!
A hassle-free and long-lived North America native. Clusters of bright yellow nectar & pollen-laden blossoms attract butterflies and the leaves shelter monarch butterfly eggs waiting for larvae to emerge – room and board provided! A must-have in every butterfly garden. Asclepias Hello Yellow, a long-blooming perennial, provides branching clusters perfect for lush summer bouquets. Slender seed pods in late summer burst open to reveal brown seeds with glistening silky threads that hitch a ride with the breeze. Butterfly weed emerges late in the spring and requires little care once established. Tough as nails!

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. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

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!

100% Guarantee

We offer a 100% unconditional guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
