Apocynum, commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek ἀπόκυνον apókunon, from ἀπο- apo- "away" and κύων kúōn "dog", referring to dogbane (Cionura erecta), which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe. Apocynum species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the queen butterfly.
