How to Grow and Care

You can also learn how to grow Lewisia from seed. The tiny plants take a couple of seasons to form a rosette but establish easily when sown in a sandy potting mixture.
Once the plants are placed in a garden situation, provide them with moderate water, excellent drainage, and a minimum of nutrients. It couldn't be simpler to grow Lewisias. The primary thing to remember is to avoid excessively fertile soil and compacted or clay situations. See more at How to Grow and Care for Lewisia.
