Eupatorium hyssopifolium, also known as Hyssopleaf thoroughwort, is a fall-blooming herbaceous plant native to North America.[2] Like other members of the genus Eupatorium it has inflorescences containing a large number of white flowers with disc florets and no ray florets.[3] At 0.5 to one meter tall,[2] it is towards the shorter end of the range of heights found in Eupatorium species.[3]
Plants which classified as E. hyssopifolium can be either diploid or polyploid, and some of them seem to have been the result of past hybridizations with Eupatorium serotinum. Hybrids with Eupatorium album and Eupatorium linearifolium also seem to exist. The hybrid Eupatorium torreyanum is similar to E. hyssopifolium but is a hybrid of E. serotinum and Eupatorium mohrii.[2]
E. hyssopifolium is found in much of the eastern United States, as far north as New York and Illinois, as far west as Texas, and as far south as Florida.[2][4] It grows in moist soils.[5]
The plant can be used medicinally (applied externally for insect and reptile bites).[5] It can also be planted near crops to attract beneficial insects.[6]
