Grows 18″ high by 16″ wide. Hardy to zone 6.
Lewisia cotyledon – This evergreen perennial requires near perfect drainage (plant on an angle) and will require a very sandy or gravely soil. It is often available in mixed strains of yellow, pink, salmon and white (in solids and stripes), so if you want orange you will have to choose them in bloom. Flowers May-June and sporadically through summer. Grows 6-8″ high. Zone 3.
