Large crowded rosette of spoon-shaped fleshy leaves, large salmon flowers. Leaves 3–6 in. long, with petioles the same length, egg-shaped to oval, entire, shiny. Spreading flower stems 4–8 in., with 1–3 flowers. Flowers apricot, pink, or white, sometimes with fine pink pencil markings. Petals 10–12, about 1 in. long, pointed or slightly notched; stamens about 15. Grows in rocky slopes or cliffs, especially with snow cover and little precipitation, at low and mid elevations only in the Wenatchee Mountains in Washington and adjacent British Columbia.
