Klamath rock daisy, Klamath Rock Daisy

Family: Asteraceae · Type: perennial · Native

Conservation status: CNPS 4.3

Klamath rock daisy is a rare (CNPS 4.3) California native perennial found in the Klamath Ranges, northern Coast Ranges, and Modoc Plateau in rocky foothills and montane forests at elevations of 1,500 to 2,700 meters. Flowering from July to September, this plant produces white to lavender daisy-like flowers with yellow centers, clustered in small heads with slender ray petals. Growing with stiff, curved stems 10 to 30 centimeters tall, it forms compact clumps with a somewhat woody base. Its leaves are narrow and lance-shaped, mostly basal, with stiff hairs giving the plant a rough, resilient texture. The dense herbage and distinctive hairy stems help distinguish this rock-loving daisy in its rugged mountain habitats.
