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] References1. ^{{cite web |url=http://www.natureserve.org/explorer/servlet/NatureServe?searchName=Asclepias+viridis |title=Asclepias viridis |website=NatureServe }} 2. ^1 {{cite web |url=http://plants.usda.gov/plantguide/pdf/pg_asvi2.pdf |title=Asclepias viridis |website=USDA Plant Guide }} 3. ^{{NPIN|code=ASVI2}} 4. ^Van Hook, T. and M.
