Cistanthe grandiflora (Calandrinia spectabilis) or Rock Purslane is a low-growing succulent from Chile with fantastic luminous pink flowers held on tall stems floating above the blue green foliage. Flowers produced over a long period in spring and summer.

Cistanthe grandiflora flowers attract bees and butterflies. The leaves are evergreen. The flowers last one day. It still produces a long flowering season due to the quantity of flowers. It grows to 60cm in tall. Cut back spent flower stems to promote more flowers.

Cistanthe grandiflora is drought-tolerant and heat-tolerant, once it is established. Grow it in full sun or partial shade. Plant it in well-drained soil. Avoid watering Cistanthe grandiflora during winter. It does well in most types of soil.
