Balsamorhiza hookeri (Hooker's balsamroot) is a North American species of perennial plant in the family Asteraceae. It grows in the Great Basin and neighboring regions in the Western United States.[2] It is found in Washington (state) , Oregon, California , Idaho, Nevada, Utah, and Arizona.[3][4][5]
Description
The leaves are compound pinnate, with the leaflet divisions also divided or deeply lobed. Basal leaves are hairy and may be up to 16 inches (41 cm) long.[2] There may be one to several stems, which are leafless and hairy, and topped by one flower each.[2][6]
It blooms from April to July. Flower heads are 1 to 3 inches (2.5 to 7.6 cm) wide, and sunflower-like, with 10–21 fringe-tipped ray flowers and numerous disc flowers.[2]
Distribution and habitat
It grows to 9,000 feet (2,700 m) in dry, grassy meadows in sagebrush steppe and montane plant communities in the Great Basin.[2] Is it abundant in Washington State scablands.
Ecology
It tends to grow in rockier habitats than its cousin, arrow-leaf balsamroot (Balsamorhiza sagittata).[2] It hybridizes with arrow-leaf balsamroot, which has arrow shaped leaves.[2] The result is a plant with leaves that are arrow shaped, but also deeply divided.[2]
