Ice Plant

“Ice Plant” is a common name encompassing a diverse group of succulent plants primarily within the Aizoaceae family, with popular genera including Delosperma, Carpobrotus, and Mesembryanthemum. While some species are annuals, many are long-lived perennials, capable of thriving for multiple years and forming extensive groundcovers. The majority of these plants are native to the arid and semi-arid regions of South Africa, where they flourish in various well-drained soils, from sandy coastal areas to rocky mountain slopes and high plateaus.

The most distinctive characteristic shared by many “Ice Plant” species is the presence of small, crystalline, bladder-like cells on their leaves and stems, which shimmer in the sunlight like dew or ice crystals ‘“ hence the common name. These specialized cells help the plant store water and reflect light, aiding in drought tolerance. Depending on the species, Ice Plants exhibit a low-growing, spreading, mat-forming, or trailing growth habit, making them excellent groundcovers. Their succulent leaves are typically fleshy and can be cylindrical, triangular, or flattened, varying in shades of green, often taking on reddish or purplish hues when stressed.

The true highlight of many Ice Plant varieties is their prolific and vibrant floral display. From late spring through summer and often into fall (and sometimes year-round in very mild climates like Phoenix), they produce an abundance of bright, daisy-like flowers that come in an astonishing array of colors, including brilliant pink, magenta, purple, red, orange, yellow, and white. These showy blooms typically open in full sun and close at night or on cloudy days, attracting pollinators like bees and butterflies. Their exceptional drought tolerance, vibrant color, and low maintenance make Ice Plants a popular choice for xeriscaping, rock gardens, slopes, and containers, especially in sunny, dry environments.
