Asclepias sullivantii, commonly called Smooth milkweed, Sullivant's milkweed or Prairie milkweed, is a perennial similar to Common milkweed (Asclepias syriaca) except smooth milkweed has (a) smooth (glabrous) stems, leaves and seed pods, (b) leaves with a significant upward sweep and distinctive reddish midveins and (c) larger flowers. It is a native plant which commonly occurs in moist prairies areas including river bottomland and moist meadowland.  Round 3" clustered star-like flowers of pinkish-white to pinkish-purple appear mostly over a long bloom period from late spring well into summer. Flowers are a nectar source for many butterflies and leaves are a food source for monarch butterfly larvae (caterpillars).


Easily grown in average, medium to wet soils in full sun. Easily grown from seed, and may self-seed in the landscape if seed pods are not removed prior to splitting open. Once established, it is best to leave plants undisturbed because they develop deep taproots which make transplanting difficult.


Native plant seeds in general do not have very high germination rates. Plant a few seeds per 1 plant desired
