This small perennial is native to western North America, where it is found in mountain environments above 2000 meters from California to Alaska to Wyoming. The plant forms cushion-like mats of small fleshy, hairy, pointed leaves in rocky crevices and on slopes. If it bolts a stem it is no taller than 15 centimeters. The flowers open in an obvious inflorescence of a few tiny blooms at times, but often appear as a layer on the surface of the mat of tiny leaves. The flowers are bright yellow with petals just a few millimeters wide. The fruit is a flat podlike silique less than a centimeter long. External links
