Antelope Bitterbrush (Purshia tridentata)
Also known as Antelope Bush, this shrub puts on quite a show in the late spring. It gets its name from its bitter taste, but deer don’t seem to mind, feeding on it regularly, often stunting its growth. The genus (sometimes called cliff-brush) is named after Frederick Traugott Pursh (1774-1820), a German gardener who, while living in the U.S., worked with collections of the Lewis and Clark Expedition and was the first to publish descriptions and engravings of the flowers they saw. For more on Pursh and the wildflowers documented by the Corps of Discovery, see our new Lewis & Clark flora page.
