About
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.
How to grow it
It can be cultivated in a wide range of areas with a Mediterranean climate. Unlike many ice plants, this species is hardy to −20 °F (−29 °C), successfully overwintering at locations such as Denver, Colorado and Chicago, Illinois. The leaves turn red in cold winter temperatures. Due to the low need for maintenance, it is suitable for urban environments and high temperature regions. It can often be found in large, extensive patches. The trailing stems also make it suitable for flowerpots and terraces.
Propagation can be accomplished by taking a flowerless cutting, stripping a couple of bottom leaves off, and then replanting in the same soil.
