Agastache scrophulariifolia, which at 4', is a tall growing member of the Mint family. Like mint, it has squarish hairy stems. The leaves are deep-green, large, and coarsely toothed, resembling those of nettles. The tiny purple flowers form a dense, showy terminal spike, or raceme.

Cultivation

Purple Giant Hyssop is found growing in moist open woods and thickets and in open floodplains. It enjoys moist rich soil in sun to part-shade. Like most members of the Mint family, it is highly adaptable, easy to grow, and will colonize with ease. It is a good choice for a cottage garden. A late season bloomer; July through September, sometimes later. Zones 4-7
