Eupatorium cannabinum, commonly known as hemp-agrimony,[2] or holy rope,[3] is a herbaceous plant of the sunflower family. It is a robust perennial native to many areas of Europe.[4][3] It is cultivated as an ornamental and occasionally found as a garden escape in scattered locations in China,[5] the United States and Canada.[6][7]
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).[8]
Description
Eupatorium cannabinum is a perennial herb up to 1.5 meters (4.9 feet) tall or more and 1.2 meters (3.9 feet) wide.[4] It lives in moist low-lying areas in temperate Eurasia. It is dioecious, with racemes of mauve flower heads which are pollinated by insects from July to early September. The flowers are visited by many types of insects, and can be characterized by a generalized pollination syndrome.[9] The flower heads are tiny, fluffy and can be pale dusty pink or whitish.[4] The fruit is an achene about 2 or 3 mm long, borne by a pappus with hairs 3 to 5 mm long, which is distributed by the wind. The plant over-winters as a hemicryptophyte.[8]
Toxicity
Eupatorium cannabinum contains tumorigenic pyrrolizidine alkaloids.[10]
