Flowers dioecious - male and female on separate plants, in tight clusters of flower heads, male flowers yellowish; female flowers are white, fluffy, and distribute seeds via the wind.
- Sun, best on well-drained soil. Drought resistant. Used for erosion control on banks. Can be mown or sheared each year to increase its density.
- Hardy to USDA Zone 8 Native along the coast from northern Oregon (B. p. var. consanguinea) to southern California, also found in the Sierra Nevada foothills. Male plants are generally preferred in landscape situations since they do not produce seed and self-sow.
