Hyssopleaf Thoroughwort: A Late-Season Native Gem for Your Garden
If you’re looking for a native plant that keeps the pollinator party going when most flowers are calling it quits for the season, let me introduce you to hyssopleaf thoroughwort (Eupatorium hyssopifolium var. hyssopifolium). This unassuming perennial might not win any flashy flower contests, but it’s got staying power and ecological value that make it a worthy addition to any native plant garden.
What Makes Hyssopleaf Thoroughwort Special?
Hyssopleaf thoroughwort is a native perennial forb that belongs to the aster family. As a forb, it’s an herbaceous plant without woody stems, making it perfect for filling in gaps in your wildflower garden or prairie restoration. The plant gets its common name from its narrow, linear leaves that resemble those of hyssop, though the two plants aren’t closely related.
This thoroughwort is also known by several botanical synonyms, including Eupatorium lecheifolium, Eupatorium linearifolium, and Eupatorium torreyanum, so don’t be confused if you see these names in older plant references.
Where Does It Call Home?
Hyssopleaf thoroughwort is a true native of the eastern and southeastern United States, naturally occurring across a impressive range of states from Connecticut down to Florida and west to Texas and Illinois. You’ll find it growing wild in Alabama, Arkansas, Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Kentucky, Louisiana, Maryland, Mississippi, New Jersey, New York, North Carolina, Rhode Island, South Carolina, Tennessee, Texas, Virginia, and West Virginia.
Why Grow Hyssopleaf Thoroughwort?
