Culture Notes Seeds will be dispersed in the late summer or early fall, and offsets will emerge in the fall at the base of the mother plant. Asclepias has a large taproot, making it difficult to transplant, and exudes a milky sap. This plant is so late to break dormancy in the spring, one might wonder if it made it through the winter. Plants serve provide nectar for butterflies and are hosts for butterfly larvae. Plant with Solidago, Heliopsis, Helianthus and Penstemon. 'Hello Yellow' tolerates dryness better than most Asclepias plants.
