About

Funastrum hirtellum, synonym Sarcostemma hirtellum, (rambling milkweed, hairy milkweed), is a perennial, vine-like plant of mid- to lower-elevation desert regions. It is a member of the family Asclepiadaceae and the genus Funastrum. It is found in the southwestern United States and northwestern Mexico — in southeastern California, southern Nevada, Arizona, Sonora, and Baja California.

Hairy milkweed can be an aggressive, opportunistic species, capable of overtaking a suitable sprouting location and killing the plants it grows upon. If the supporting plants can compete successfully, all of the species continue.
