Hardy Ice Plant

delosperma_hardy-ice-plant_xg_lah_2583Covering the ground with a solid mass of eye-searing fuchsia-purple flowers, Hardy Ice Plant (Delosperma cooperi) demands a second look. The succulent green leaves glimmer in the sun, giving the plant its common name, while the flowers have glistening thin petals surrounding a yellow center.

Waves of bloom carpet the foliage from late spring until late summer. The show even continues in winter, when plants turn a deep burgundy-red. Other species of Delosperma, with yellow or salmon-pink flowers, are also now available. Some have earned PlantSelect® honors.

Hardy Ice Plant is very easy to grow in full sun. Well-drained soil is essential; the roots will rot if kept constantly damp. If rainfall is inadequate, add enough water to thoroughly moisten the root zone, then let dry completely before watering again. Fertilize sparingly. Plants should survive temperatures to -20° F. New plants may be started from cuttings, or buy plugs at a garden center.

Give it room to spread; you may have to restrain it occasionally. It’s also an excellent groundcover for small-to-medium areas, particularly next to walkways. Consider companions with gray foliage that won’t compete with Delosperma’s intense flower colors—or look for equally vivid flowers in complementary hues.

  1. For some reason, ice plant is just one of those plants I am not allowed to have in my garden. I have spent many dollars on it over the years….none survive.

  2. How odd. It grows so well at the Xeriscape Demo Gardens! I love it, but it’s a real pain to weed, since you can’t get near the roots.
