Asclepias verticillata is an upright plant with very narrow, needle-like leaves on unbranched stems. Asclepias vericillata forms clusters of fragrant white blooms that are held in the upper leaf axils and on stem ends. It is one of the last species of milkweed to bloom. Commonly referred to as Whorled Milkweed, this is a rhizomatous perennial plant that will spread to form colonies.
Whorled Milkweed is native to the eastern two thirds of North America, where it is typically found in open areas such as prairies, grassy woodlands, limestone glades, rocky bluffs, roadsides and along railroad right of ways.
Whorled Milkweed prefers full sun to part shade and average to dry soil. Asclepias verticillata is a host to Monarch caterpillars and its flowers make a good nectar source.
