Apocynum, commonly known as Indian hemp, is a genus of the plant family of the Apocynaceae with seven species. Its name is from the Greek: apo, away and cyno, attributed to its toxicity. The genus is native to North America, temperate Asia (China, Siberia, Kazakhstan, etc.), and SE Europe (Italy, Bulgaria, Ukraine, etc.). Apocynum species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the Queen butterfly.
