A low, gray cushion of tiny, narrow leaves subtends a short, erect, leafless flowering stalk, 1-5 in. tall. A small, grayish, hairy, densely tufted plant with basal leaves and racemes of small yellow flowers on leafless stalks. Forms mats to 3 ft. across. Tiny, yellow flowers occur in dense, showy clusters and fade to creamy white.
This is one of many tufted species of Draba with yellow flowers, distinguished in part by technical characteristics of the hairs. The entire surface of this plant is covered with microscopic hairs that lie flat, each with a main axis and perpendicular branches on either side (similar to two back-to-back combs).
