Delosperma cooperi

Delosperma cooperi (syn. Mesembryanthemum cooperi), the trailing iceplant, hardy iceplant or pink carpet, is a dwarf perennial plant native to South Africa. It forms a dense lawn with abundant, long-lasting flowers. It reaches sizes of approximately 10–15 cm (4–6 in) tall, with fleshy leaves that are linear and simple and can grow up to 1.5 inches long and a trailing stem that hangs down. These fleshy roots help provide the ability for the plants to recover and grow rapidly if a disturbance has occurred....read more on Wikipedia.
