Grows as rosettes of long, narrow, fleshy leaves with the pure white flowers tucked between the leaves in the centre of the plant. The flowers only open wide in full sunshine but it is worth the wait for a good day in mid spring.
This as a deciduous species - the leaves yellow and die back in summer and the plant retreats below ground to re-emerge in February. Unlike most Lewisias, it will tolerate moist soil - we over-winter ours outside, unprotected but in well-drained compost. About 5cm (2") high. Ideal in a stone trough.
