Artemisia is a large, diverse genus of plants comprised primarily of hardy herbs and shrubs that grow in temperate, dry or semi-dry habitats. This genus includes commonly known shrubs such as sagebrush, wormwood, and tarragon, and most members of this genus contain volatile oils that produce strong aromas and bitter tastes when crushed. Artemisia pollen is commonly recovered from late Pleistocene sites across the Midwest, possibly representing Prairie sagebrush (Artemisia frigida) - an aromatic, mat-forming, semi-evergreen shrub that is commonly found in dry and disturbed habitats today.
