Asclepias amplexicaulis

Asclepias amplexicaulis, the blunt-leaved milkweed, clasping milkweed, or sand milkweed, is a species of flowering plant in the subfamily Asclepiadoideae (Apocynaceae).[1][2] It is endemic to the United States, where it is mostly found east of the Great Plains.[3] It grows in dry prairies, savannas, open woods, and fallow fields, usually in sandy soil.[2][4][5]


It grows 1–3 ft (0.30–0.91 m) high and produces flowers in the summer.[4]

This plant was eaten as food historically. However, it contains a poison dangerous to humans and livestock, so caution must be used if ingesting this plant.[6]
