A shrub, three or four feet tall, which grows on dry rocky hillsides,
often associated with sagebrush. The flowers are creamy yellow,
have 5 petals, and are about a half inch across. They bloom in the
spring.
Each blossom has many stamens and one pistil, from which a single
hard dry bitter fruit is produced.
Bitterbrush is a favorite food plant for many animals, so it is
often found to be browsed and nibbled down extensively.
The genus name is in honor of Frederick Pursh (1774-1820).
He examined and classified many of the specimens collected by the
Lewis and Clark expedition, and produced the first plant book
covering North America.
