Douglas' coreopsis

Family: Asteraceae · Type: annual · Native

Douglas' coreopsis is a California native annual found in the eastern San Francisco Bay Area, southern Coast Ranges, and northern Western Transverse Ranges on dry, rocky slopes at elevations of 150 to 600 meters. Flowering from March to May, this plant produces yellow ray flowers 5 to 12 millimeters long surrounding a compact disk of smaller flowers. Growing 5 to 25 centimeters tall with 1 to a few erect, glaucous stems, it has a distinctively glabrous appearance. Its leaves are linear, 2 to 8 centimeters long and only 1 millimeter wide, with a slightly fleshy texture and a grooved upper surface. The plant produces small, shiny dark brown fruits with a subtle yellow wing, characteristic of its delicate coreopsis form.
