Eupatorium cannabinum

Eupatorium cannabinum, commonly known as hemp-agrimony, or holy rope, is a herbaceous plant in the family Asteraceae. It is a robust perennial native to Europe, NW. Africa, Turkey, Syria, Iran, Iraq, Jordan, the Caucasus and Central Asia. It is cultivated as an ornamental and occasionally found as a garden escape in scattered locations in China, the United States and Canada. It is extremely attractive to butterflies, much like buddleia.

If the genus Eupatorium is defined in a restricted sense (about 42 species), E. cannabinum is the only species of that genus native to Europe (with the remainder in Asia or North America).
