Notes: Photographed Oct. 14, 2007 on a desert road near Oatman, Ariz. A perennial herb that is native to California and is also found outside of California to Nevada, Arizona, n Mexico, but is confined to western North America. The sap has been analyzed and found to contain rubber. In Mexico, the toxic milky juice is used as an emetic and purgative. This milkweed is particularly noticable as it sways in the breeze on slender stems.
