About Erigeron coulteri Porter & Coult.
Erigeron coulteri Porter & Coult. is a species of flowering plant in the Asteraceae family, with common names including large mountain fleabane, Coulter's fleabane, and Coulter's daisy. It is native to most of the western United States, where it grows in moist forests and meadows. Populations have been recorded in California, Nevada, Colorado, New Mexico, Wyoming, Montana, Oregon, and Idaho, with large areas of land between these known populations. This plant is a perennial herb that grows to a maximum height between 20 and 70 centimeters, or 8 to 28 inches. It produces an erect stem that may have a small number of branches or none at all. Leaves grow both at the base of the plant and along the stem. The long leaves range from somewhat lance-shaped to more rounded, and sometimes have a small number of teeth along their edges. At the top of the stem, the inflorescence holds between one and four flower heads, each 1 to 2 centimeters (0.4 to 0.8 inches) wide. The center of each flower head is filled with tiny golden yellow disc florets, and the outer edge is fringed with up to 140 white ray florets.
