DistributionThe wildflower is endemic to northern California and far southern Oregon. It is known from the rocky, barren serpentine slopes of Mt. Ashland of the Siskiyou Mountains and the Klamath Mountains and Northern California Coast Ranges. It is found in Yellow pine forest and Red fir forest associations. DescriptionClaytonia saxosa is a small, compact annual herb forming clumps a few centimeters wide in rock crevices. Serpentinite is the favored geologic substrate of this species. The leaves are small, with fleshy spatulate blades. The basal leaves and flowering stems are pink or red in color, packed densely together about the short stem that surmounts a minute, tuberous caudex. The chromosome number of the species is 2n = 16.[1]Two to ten flowers emerge from the clump, each with five light pink petals under a centimeter long. The bloom period is March to May.
