1-2" tall x 15-18" wide. Delosperma cooperi (Cooper’s Hardy Ice Plant) spreads to form a low mat of succulent foliage and blooms much of the summer with large magenta-pink flowers. This is the original Cold Hardy Ice Plant introduced in the early 1990s through the Denver Botanic Garden. Its introduction started the keen interest in Ice Plants for use in the Intermountain and western areas of the US. An excellent groundcover, it likes summer irrigation in dry climates to bloom and grow well. Use gravel mulch to keep the branches and crown of the plant dry in winter.
