Whorled Milkweed

3 Photos


Summary

Whorled milkweed 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.  It 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 to release seeds attached to numerous silky white hairs. Some companions for this early to mid-summer bloomer include Echinacea pallida, Rudbeckia fulgida, Euthamia caroliniana, and Andropogon virginicus.
