Asclepias verticillata

Native Plants

Whorled Milkweed

3 Photos


Whorled milkweed (Asclepias verticillata) is an attractive 1-2’ tall perennial with clusters of 10-20 small, greenish-white flowers in the axils of the upper leaves. It is distinguished from other milkweeds by its smooth, needle-like, whorled leaves arranged on a generally unbranched stem. Whorled milkweed prefers full sun and handles dry, infertile soil well. It will grow in richer soils under more moist conditions but spreads quickly by rhizomes, so is best used where colonies are desired. The seedpods are ornamental when they open,  releasing  seeds attached to numerous silky white hairs. Some companions for this early to mid summer bloomer include pale purple coneflower(Echinacea pallida), black-eyed Susan (Rudbeckia fulgida), slender goldentop (Euthamia caroliniana), andbroomsedge bluestem (Andropogon virginicus). Zones 4-9.
