Summary

Mesembryanthemum cordifolium, commonly known as heart-leaf iceplant, is an evergreen perennial herb or subshrub native to coastal dunes and sandy areas in Eastern South Africa, extending to KwaZulu-Natal. It is a member of the Aizoaceae family, characterized by its succulent nature. The plant forms a creeping, mat-like ground cover from a woody base, with stems that can reach up to 60 centimeters (24 inches) long, while the height is typically around 10 centimeters (3.9 inches). The heart-shaped, fleshy leaves are a distinctive feature, and the bright pink to purplish flowers are solitary, appearing in the leaf axils. These blooms open during the day and close at night or during cloudy weather, with a flowering season that extends from spring to fall. The flowers are moderately showy, adding a splash of color to the landscape.

The heart-leaf iceplant is valued for its drought tolerance, rapid growth, and ability to suppress weeds, making it an excellent ground cover. It thrives in sunny locations with well-drained soil and is often used in rockeries, as a ground cover in traffic islands, and in hanging baskets where its trailing branches can cascade attractively. While it is not frost-hardy, it can be grown in containers in colder regions. Care should be taken when planting this species, as it can become invasive outside its native range, potentially disrupting local ecosystems.CC BY-SA 4.0
