A perennial herb, 1.5-3 dm tall, distinctively pallid in color. The spatula-shaped leaves and the calyx lobes are conspicuously white-margined. Flowers (March-May) are pink-lavender with darker purple accents.
Distribution & Occurrence
In California, this plant occurs in fine alluvial sand in a wide canyon within a creosote bushscrub community. The sand is deep and stabilized, holding the long taproot in place. It is also present in wind-blown sand at the head of the canyon. It occurs at elevations from 2000-3000 ft. (700-1000 m.) in alkaline soil (Scogin, 1989). In Nevada, the plants prefer the base of hills and mountains in wind-blown sand dune-like areas, but are also found in deep loose sand in wash bottoms. In Arizona, it occurs in sandy loam uplands and sandy washes in a broad alluvial plain, but gravelly areas alternating with and interspersed with the sandy places do not support this species.

Conservation, Ecology & Research
More propagation studies should be carried out to determine if seedlings, cuttings, or transplanted plants could be used for mitigation efforts.
