Comments

Blooms July-November. Slender, leafy, much-branched stems bearing several yellow, daisy-like flower heads. The prickly fruit of Bidens species are known as beggars’ ticks for the two-pronged “stickers” that cling to clothing in the fall. Attracts: bees, birds and butterflies. Larval Host: Dainty Sulphur.
Previous Scientific Name(s): Synonym(s): Bidens aristosa var. fritcheyi, Bidens aristosa var. mutica, Bidens aristosa var. retrorsa, Bidens involucrata, Bidens polylepis, Bidens polylepis var. retrorsa
