Agastache scrophulariifolia, or Purple Giant Hyssop, is native to central-midwestern US, as well as the Great Lakes area and the northeastern US, extending into the Appalachian area as well. It is a perennial that grows in open woods, along woodland edges and in thickets.

This plant is similar to another, which also overlaps in its range: Agastache foeniculum. The two can be distinguished by the lighter purple flowers of Agastache scrophulariifolia, where Agastache foeniculum usually has deeper purple and can have shorter stalks as well. Additionally, Agastache scrophulariifolia has green calyxes around the flowers - that is, the small leafy enclosure at the end of every flower; Agastache foeniculum lacks this green calyx feature.
