Lewisia is one of those plants that breaks your heart. Named for Meriwether Lewis, Lewisias are succulent plants native to the mountains on the West Coast. The variety commonly available at nurseries is Lewisia cotyledon ‘Sunset Strain’.
In this manner, how do you care for a Lewisia?
Lewisia will need sufficient protection from winter moisture as excessive wet will damage the roots. Provide a monthly feed during the growing season using half strength all purpose fertiliser. If watered regularly, many hybrid varieties will flourish two to four times further during the growing season.
Herein, how often should I water my Lewisia?
Spread a 2- to 3-inch depth of mulch beneath the plants. Continue to water them once or twice each week during the spring, summer and fall in the absence of rainfall. Keep the soil uniformly moist. Do not water them throughout the winter.
How does Lewisia spread?
Some Lewisia plants have flowers that are altogether white. The flowers bloom in clusters atop long, fleshy stalks (from ground level to the flower tops, the plants stand about 8 inches tall). The plants can spread by having a “mother plant” send out babies (what horticulturists term “offsets”) directly from itself.
Lewisia is hardy in USDA zones 3 to 8. There are several species available and this native of North America performs well in alpine gardens, rockeries, planters, or even along a gravel path. … They are found in nature in pine forests, rocky mesas, and gravel hillsides.
A clump-forming perennial, with fleshy rosettes of dark green leaves. Flowers prolifically for a long period if deadheaded regularly from spring to summer.
Caring for Lewisia
In spring and early summer the ‘Sunset hybrids’ produce open funnel shaped flowers in large panicles over a lengthy flowering period. … Although they flower best in full sun a little shading or protection from direct sunlight is advisable under glass.
Detach offsets and plant them in a mixture of equal parts (by volume) peat and sand in half pots (pans) and place them in a cold frame. When rooted, pot into 75mm (3″) pots of potting compost. Overwinter them in a frost free coldframe until planting out time.
Lewisia cotyledon is the best known of the bunch and probably the easiest to keep happy. It will grow out in the garden, but needs to be planted on its side so that winter wet cannot rot the leaf rosettes. I find that if I do that, slugs eat them anyway.
The preferred season for transplanting Lewisia cotyledon is in spring. Make sure to transplant it outdoors. The small plant rarely grows to the size needed for transplanting into a large container and therefore must be moved to a compact hypertufa container.
