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]
