Calandrinia grandiflora (Rock Purslane)

Rock Purslane, Cistanthe grandiflora, Claytonia grandiflora


Quite showy, Calandrinia grandiflora (Rock Purslane) is a succulent plant forming a mound of fleshy, narrowly oval and pointed blue-green leaves, 4-6 in. long (10-15 cm). From spring into fall, it produces a breathtaking display of brilliant magenta flowers along tall, slender stems above the evergreen foliage. Floating above the leaves, the flowers last only one day, but there are several buds on the stems that open up one at a time over a long blooming period. Sturdy, resilient to pests and diseases, heat and drought tolerant, this gorgeous succulent is terrific when planted en masse in front of borders or as a focal point in rock gardens and containers.

  • Typically grows up to 1-3 ft. tall (30-90 cm) and 2-3 ft. wide (60-90 cm).
  • Performs best in full sun to part shade, in well-drained soils with occasional irrigation. Drought tolerant once established. Withhold water during winter dormancy.
  • Rock Purslane is hardy to USDA 9 - 11 and grown as an annual in cooler areas.
  • Propagate by cuttings in spring.
  • Native to Chile
