Ice plants, also known as Delosperma, are succulent plants that are native to South Africa. Because they are succulent, they require very little water and enjoy hot dry areas. Ice plants are hardy between USDA plant hardiness zones 5 to 11, but they will only grow as perennials in zones 7 and below while they will grow as evergreens in zones 8 and higher. The best place to grow an ice plant is in a desert or rock garden.
Plant the ice plant in the spring after the last frost. Ice plants need well-drained soil, but they can handle all soil types. Ice plants also need full to partial sun. Dig a hole as deep as the root ball and twice as wide. Place the ice plant in the hole and fill it with soil.
Water the ice plant once every week. Allow the soil to dry out completely between each watering.
Fertilize ice plants once a season with a water soluble cacti fertilizer diluted to a quarter strength.
Divide ice plants in the spring for propagation, if desired.
