Artemisia biennis

Summary 2

Artemisia biennis is a species of sagebrush known by the common name biennial wormwood. It is a common and widely distributed weed, so well established in many places that its region of origin is difficult to ascertain. One source (Flora of North America) maintains that the species is most likely native to northwestern North America and naturalized in Europe, New Zealand, and eastern and southern North America.
