Erigeron compositus is an Arctic and alpine species of fleabane in the daisy family.[1] Common names include dwarf mountain fleabane, cutleaf daisy, and trifid mountain fleabane[2][3]
Erigeron compositus has been found in the Russian Far East (Wrangel Island and Chukotka), Alaska, Greenland, much of Canada (all 3 Arctic territories plus British Columbia, all 3 Prairie Provinces, Quebec, Newfoundland, and Nova Scotia), and the western United States (from the Pacific Coast as far east as the Dakotas, Colorado, and New Mexico).[1][4]
Erigeron compositus is perennial herb rarely more than Vorlage:Convert tall. It produces a taproot and spreads by means of horizontal underground rhizomes. A plant generally produces only one flower head per stem, each head with 20–60 white, pink or blue ray florets, these sometimes small and easily mistaken for disc florets. Genuine disc florets are yellow and in the center of the head.[5]
