Rank ReasonsPurple giant-hyssop (Agastache scrophulariifolia) occurs in eastern North America in the United States and southeastern Canada, from Minnesota and eastern Kansas to southern Ontario, New York and southern New England, and south in the Southern Appalachian Mountains to Georgia. It is estimated that there are over 300 occurrences rangewide, including on the Chattahoochee, Cherokee, George Washington, and Monongahela National Forests, Shenandoah National Park, Minnesota Valley National Wildlife Refuge, and on various state wildlife management areas, State Parks, and State Forests. Threats to this species include the loss of high quality forested habitat and conversion of natural forests to commercial forests.
Range Extent CommentsPurple giant-hyssop (Agastache scrophulariifolia) occurs in eastern North America in the United States and southeastern Canada, from Minnesota and eastern Kansas to southern Ontario, New York and southern New England, south in the Southern Appalachian Mountains to Georgia. Range extent was estimated to be 1,431,000 square kilometers, using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024, Weakley and Southeastern Flora Team 2023).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 300 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsLoss 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 (including Connecticut, Massachusetts, Vermont, Maryland and Nebraska) (Southern Appalachian Species Viability Project 2002).
