Agastache scrophulariifolia, also known as the Purple giant hyssop, is a perennial plant that grows throughout the US and Northern Ontario, CN. It is a beneficial plant to pollinators and is noted for its medicinal properties, as many plants in the mint family are. It tends to grow in disturbed or open areas where it does not have to interact with non-native competitive plants.

Individuals of this species are perennial herbs that can grow up to six feet tall. They are late-flowering species in the mint family. Agastache scrophulariifolia tends to have several spiked inflorescence. Flowers of Agastache scrophulariifolia do not all bloom simultaneously and range from lavender to pink in color. The dark brown fruit they produce is a nutlet.
Agastache scrophulariifolia was once distributed throughout CT, DC, DE, GA, IA, IL, IN, KS, KY, MA, MD, MI, MN, MO, NC, NE, NH, NJ, NY, OH, PA, SC, SD, TN, VA, VT,WI, WV, and ON, Canada. However, its range is now severely reduced in many areas and in some cases extirpated completely. These declines are largely due to habitat loss, predation by deer, and competition for resources with non-native plants. This plant is endangered in the state of Connecticut.
Agastache scrophulariifolia tends to grow in riparian habitats, disturbed open areas, and meadows. The previously mentioned areas are ideal for Agastache scrophulariifolia because competition with other plants is reduced. As riparian habitats are altered or farmlands return to forest communities, Agastache scrophulariifolia suffers from habitat loss. It is a perennial plant that grows well in sandy loamy soils and requires sunlight for its seeds to germinate.
Many people use this plant for its aromatic effects.
The Meskwaki use an infusion of the root as a diuretic, and also used a compound of the plant heads medicinally.
