Apocynum × floribundum, the intermediate dogbane, is a member of the family Apocynaceae. It is widespread across Canada, the United States, and northern Mexico.[1][2][3][4]

Intermediate dogbane is believed to be of hybrid origin because its characteristics are intermediate between A. cannabinum (dogbane) and A. androsaemifolium (spreading dogbane).[1]
