Scientific classification

Grindelia hirsutula is a North American species of flowering plant in the daisy family known by the common names hairy gumplant and hairy gumweed.


Grindelia hirsutula is native to North America, widespread across Canada and in California and Oregon. The species is highly variable, and many local populations have been named as varieties or as distinct species. All these taxa do, however, intergrade with one another.


Grindelia hirsutula is an erect perennial herb or subshrub sometimes as much as 250 cm (100 inches or 8 1/3 feet) tall but usually much shorter. The plant is usually green but the stems are often red or purplish-brown and the leaves can be somewhat yellowish to reddish.

The plant can produce numerous flower heads in branching arrays at the top of the plant. Each head is 2 or 3 centimeters (0.8-1.2 inches) wide with hemispheric cups of greenish phyllaries around the base, the bracts claw-like and bent away from the flowers. The center of the head is filled with many small yellow disc florets surround by numerous golden ray florets. The head produces a thick white exudate, especially in new flower heads.
