Description
Rock purslane is a small mounding succulent with thick blue-green foliage that grows to 12 in. high and spreads 2-3 ft. across. Colorful and intense purple-magenta flowers to 2 in. dia. develop on flexible stems from mid to late spring and intermittently into summer.
Native to Chile, Rock purslane belongs to a small group of succulents with colorful flowers and a tolerance for arid conditions. It is the only species commonly found in cultivation in California where it is a popular accent plant in rock gardens and among other succulents. Both foliage and flowers offer a contrasting character to most plants, particularly with its intense purple-magenta flowers.
This is a short-lived perennial that grows well for 2-3 years. It does best in well-drained soils and away from the hottest sun. It flowers best with regular water through the end of spring and less during summer.
Water Needs
Rock purslane is well adapted to all parts of the Inland Empire in sunny exposures with normal winter rains and low amounts of summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains often provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates Rock purslane can grow with varying amounts of water, but is not well adapted to weeks of drought stress.Irrigation Schedule and Graph
