This well-known species exists in many varieties, some with rather lurid colours. All have rosettes of fleshy leaves, and can in time form large mounds, from which many stems emerge, each with many flowers. They are best grown in a position where water cannot reside in the rosettes in winter.

Lewisia Brynhyfryd white special is a cross of the hybrid of Lewisia cotyledon with L. longipetala, which is normally sterile, with itself. The progeny of this unusual marriage has white flowers and is fertile, and its offspring then come true from seed, so it is probably a tetraploid. The hard work behind this development was done at Brynhyfryd Nursery on the Welsh-English border, whence all sorts of interesting lewisias have emerged.
