Asclepias viridis

Asclepias viridis is a species of flowering plant in the dogbane family known by the common names green antelopehorn and spider milkweed. It is native to the southcentral and southeastern United States.[1]

This milkweed is a perennial herb with alternately arranged leaves. The inflorescence is an umbel of white flowers with purplish centers.[2] Its root system is a taproot,[3] like that of butterfly milkweed (Asclepias tuberosa).

This species grows on many types of soil. It is common in overgrazed pasture land and roadsides.[2]

This, like some other milkweed species, is a host plant for the monarch butterfly.[4]
