Asclepias albicans

Asclepias albicans S. Watson

Whitestem Milkweed, White-stemmed Milkweed

Asclepiadaceae (Milkweed Family)



USDA Native Status: L48 (N)

Tall, leafless, waxy-white stems with woolly umbels of whitish, star-like flowers on branches near top; sap milky.

The genus was named in honor of Asclepiades, a physician in ancient Greece, undoubtedly because some species have long been used to treat a variety of ailments. The similar Rush Milkweed (A. subulata) is found in the same region in desert washes and on sandy flats; it is distinguished by its narrow, erect hoods, which are about as long as its petals.
