Trelease's draba

Family: Brassicaceae · Type: perennial · Native

Trelease's draba is a California native perennial found in the northern Sierra Nevada Mountains on open, rocky slopes, talus, and scree at elevations of 1,500 to 3,700 meters. Flowering from June to August, this plant produces small, bright yellow flowers about 2 to 4 millimeters wide in compact clusters. Growing as a tufted, cushion-forming herb with unbranched stems less than 4 centimeters tall, it forms dense, low-growing mats of vegetation. Its basal leaves are small, oblong to linear-oblanceolate, densely covered with multi-rayed hairs, and range from 2 to 8 millimeters long. The fruit is a slightly inflated ovoid capsule 3 to 4 millimeters long, covered in distinctive multi-rayed hairs that give the plant a unique textured appearance.
