Balsamorhiza hookeri (Hooker's balsamroot) is a North American species perennial plant in the sunflower family. It grows in the Great Basin and neighboring regions in the western United States.[2]:115 It is found in Washington, Oregon, California, Idaho, Nevada, Utah, and Arizona.[3][4][5]
Description
Leaves and stems
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]:115
The stem is leafless and hairy.[2]:115
Inflorescence and fruit
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]:115
Habitat and range
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]:115
Ecological interactions
It tends to grow in rockier habitats than its cousin, arrow-leaf balsamroot (Balsamorhiza sagittata).[2]:115 It hybridizes with arrow-leaf balsamroot, which has arrow shaped leaves.[2]:115 The result is a plant with leaves that are arrow shaped, but also deeply divided.[2]:115
