Stems: scape short, jointed, bracteolate near the middle. Leaves: linear-oblong, subterete, smooth, glaucous.

The large showy rose-pink flowers of this Lewisia are very lovely. The oblong, narrow leaves, which are crowded at the crown of the thick caudex, are smooth and covered with a whitish bloom; while from a fleshy root grow the one-flowered buff-coloured scapes that are jointed and have buff bractlets near the middle.
