The plant generally produces only 1 flower head per stem. Each head has 40–70 purple or pale blue ray florets surrounding numerous yellow disc florets. The plant grows on buffs, ledges, and steep slopes at high altitudes, often above tree line.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250066653 Flora of North America, Erigeron pinnatisectus (A.
