The natural range is small but split between 3 counties in 3 states: Malheur County in Oregon, Owyhee County in Idaho, and Elko County in Nevada.[2]Erigeron latus is a small perennial herb rarely more than 8 centimeters (0.8 inches) tall, producing a woody taproot. The leaves are mostly crowded around the base of the stem. Both the stem and the leaves are covered with stiff hairs. The plant generally produces only one flower head per stem, each head with up to 25 purple or pink ray florets surrounding numerous yellow disc florets.[3] References1. ^The Plant List, Erigeron latus (A.Nelson & J.F.Macbr.)
