Information About the Hardy Ice Plant The hardy ice plant (Delosperma) is a succulent, perennial ground cover with daisy-like flowers. The ice plant is not called an ice plant because it is cold hardy, but rather because the flowers and leaves seem to shimmer as though covered in frost or ice crystals. The plants grow to be about 3 to 6 inches (7.5 to 15 cm.) tall and 2 to 4 feet (0.5 to 1 m.) wide.
