Botanical Description

Bidens tripartita, the trifid bur-marigold or water agrimony, is an annual herb of the family Asteraceae growing 15 to 60 cm tall, with erect, often reddish, branching stems. The leaves are opposite and characteristically divided into three to five lance-shaped, toothed lobes, the central lobe largest, on winged stalks. The flower heads are erect to nodding, button-like and lack conspicuous ray florets, consisting of a flat disc of dull yellow-brown florets surrounded by leaf-like spreading bracts. The flattened achenes bear two to four backward-barbed bristles that cling to fur and clothing. It flowers from mid summer into autumn. Native across Europe and temperate Asia and naturalised elsewhere, water agrimony grows on wet, muddy ground at the margins of ponds, ditches, rivers, marshes and damp fields.
