Quick Summary
The hairy willow herb (Epilobium hirsutum) is a European plant known for its stout, hairy stem and rose-purple flowers. It can grow up to 2 meters (6 feet) tall and is sometimes found in waste places in eastern North America.12
This plant belongs to the Epilobium genus, which comprises about 200 species native to temperate regions and is part of the evening primrose family, Onagraceae. While similar to fireweed, the hairy willow herb is distinguished by its hairy leaves and stalks, as well as notched flower petals. The taxonomy of Epilobium is still debated, with some species formerly included in the fireweed genus.2
