Agoseris grandiflora var. leptophylla

Giant mountain dandelion

Family: Asteraceae · Type: perennial · Native

Giant mountain dandelion is a California native perennial found in northwestern California's Klamath Ranges in coastal prairie, grassland, meadows, and forest at elevations of 100 to 1,500 meters. Flowering from May to June, this plant produces yellow flowers with rosy-purple and purple-spotted involucre heads 2 to 4 centimeters long. Growing with slender stems 30 to 60 centimeters tall, it develops a delicate, elongated form. Its leaves are distinctively narrow, 2 to 4 millimeters wide, linear to linear-oblanceolate with thread-like or lance-linear lobes that taper elegantly. The plant's intricate, thread-like leaf structure and rosy-purple involucre make it a unique grassland wildflower.
