Helianthus pumilus
Also called Dwarf Sunflower
Helianthus pumilus, the little or bush sunflower, is a small North American perennial native to dry, rocky mountain slopes and plains of Wyoming, Colorado and Montana. It grows best in full sun and lean, well-drained soil, where it needs little water once established.
Helianthus pumilus is a North American species of sunflower known by the common name little sunflower or bush sunflower. It is found in the western United States, primarily the Rocky Mountain region of Montana, Wyoming, and Colorado, with a few isolated populations in Utah and Idaho.
