Description
This milkweed, Asclepias erosa, is a perennial herb with erect yellow-green stems and foliage in shades of pale whitish-green to dark green with white veining. It may be hairless to very fuzzy. The sturdy, pointed leaves grow opposite on the stout stem. Atop the stem is a rounded umbel of yellowish or cream-colored flowers. Each flower has thick, reflexed corollas beneath a flower center composed of rounded, horned filaments.
Uses
The plant is filled with a viscous sap that was roasted to a solid and enjoyed as a sort of chewing gum by local Native American groups. Researchers in Bard, California tested the plant as a potential source of natural rubber in 1935.[1]
Butterflies
Asclepias erosa is a specific monarch butterfly food and habitat plant.
