National NatureServe Conservation Status
Rounded National Status Rank: N1 - Critically Imperiled
Rounded National Status Rank: NNR - Unranked
NatureServe Conservation Status
Rounded Global Status Rank: G4 - Apparently Secure
Comments: Loss of high quality forested habitat and conversion of natural forests to commercial forests are threats to this species of limited distribution which is imperiled in many states without secure populations (CT, MA, VT, MD and NE); (Southern Appalachian Species Viability Project 2002).
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.
Habitat and Ecology
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.
Essential oils from Agastache scrophulariifolia were used by the Meskwaki tribe for their diuretic effects. Many people also use this plant for its aromatic effects.
