Ice Plants: A Beginner’s Guide to Growing and Nurturing

Ice plants are a diverse genus of warm-weather perennials known for their vibrant flowers. The two most popular genera are Lampranthus and Delosperma, both of which are characterized by fleshy, succulent foliage and tiny hairs that reflect light like ice crystals. These fast-growing plants bloom in spring and continue to flower throughout the growing season. In cooler climates, it’s best to plant them by midsummer, while in hotter areas, fall planting is more suitable.

Ice plants can grow as everything from a spreading ground cover to a bushy subshrub, depending on the type. They work well in sunny, sheltered desert gardens, on slopes, in rock gardens, or as ground cover or edging plants. With proper care, they can spread up to 2 feet or more and thrive in containers. For optimal growth, plant ice plants in locations that receive plenty of sunlight and have fast-draining soil. Space plants 15 to 18 inches apart, and prune out any winter-killed stems every spring.

Ice plants require plenty of direct sunlight to bloom well, and providing at least six hours of it is crucial. These plants do not thrive in constantly moist conditions or dense clay soil, so ensure the soil has excellent drainage, preferably sandy or gravelly. During the growing season, water the ice plants sparingly, with one watering every two weeks being sufficient. Weekly watering might be needed during hot weather, but make sure the plant dries out before winter to avoid moisture buildup. Ice plants are sensitive to cold temperatures, so check their hardiness range before planting. While they don’t need rich soil, compost or a slow-release fertilizer can be beneficial for container-grown ice plants. Propagation is easy through division or allowing natural spread, and they grow well in any well-draining potting mix. Some common problems include root rot due to overwatering, yellowing leaves, and pests like aphids and mealybugs. Deadheading doesn’t have much effect on blooming, but providing plenty of light and occasional fertilization can encourage it.
