Grindelia hirsutula
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.
