Botanical Description

forming dense mats with flowering stems rising to 10cm tall. Leaves thick and firm, strongly glaucous, glabrous or spreading-hispidulous, irregularly and often inconspicuously serrulate, subrotund to broadly elliptic or obovate, 8-18mm long. Flowers 2.5-3.6cm long, pink or nearly red to pink-lavender or rose-purple. On cliffs, ledges, and rocky slopes, usually fairly well up in the mountains, but descending to lower elevations in the Columbia River Gorge, Washington to northern California. Apparently hybridizes freely with P. davidsonii where the two come into contact. Superlative rock plant for a cool crevice.
