Landscape Attributes

Rainbow Mix Lewisia is an herbaceous evergreen perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a high maintenance plant that will require regular care and upkeep, and should not require much pruning, except when necessary, such as to remove dieback. It has no significant negative characteristics.

Rainbow Mix Lewisia is recommended for the following landscape applications:

• Rock/Alpine Gardens
• Border Edging
• General Garden Use

Planting & Growing

Rainbow Mix Lewisia will grow to be only 6 inches tall at maturity extending to 10 inches tall with the flowers, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 5 years.

This plant should only be grown in full sunlight. It requires an extremely dry, well-drained growing location, and will usually die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil pH, but grows best in sandy soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selection of a native North American species.
