Mountain agoseris
Family: Asteraceae · Type: perennial · Native
Mountain agoseris is a California native perennial found in the Klamath Ranges, high Cascade Range, Sierra Nevada, Warner Mountains, and White and Inyo Mountains in subalpine meadows, forest, and alpine tundra at elevations of 1,500 to 3,800 meters. Flowering from July to August, this plant produces bright yellow flowers in heads 10 to 20 millimeters long with distinctive rosy-purple involucres. Growing with decumbent to prostrate stems 2 to 25 centimeters tall, it forms low-spreading clusters across rocky alpine terrain. Its leaves are typically 2 to 10 centimeters long, narrowly to broadly oblanceolate with 2 or more pairs of linear to oblanceolate lobes, and are often densely hairy with white or yellow translucent hairs. The fruit is a narrowly fusiform body 6 to 9 millimeters long with a short 1 to 3 millimeter beak.
