Alpine yellow ice plant shows off rich yellow, gold, and sometimes orange blooms spring through fall, similar to Delosperma congesta (compact yellow ice plant). The foliage of these two ice plants are quite different, however. Delosperma nubigenum is fast growing with long, trailing stems. In full sun or in winter cold, the bright green leaves take on a red hue.
Also called hardy yellow ice plant, Delosperma nubignenum is a particularly cold-tolerant species of this genus. In Latin, “nubigenum” means “cloud-born”, or “cloud-dweller”, and refers to the plant’s high alpine origin.
Hardy ice plants (Delosperma sp.) are low-growing succulents native to the alpine regions of southern Africa. While sporting attractive groundcover foliage, they are best known for their multitude of aster-like blooms. Ice plants work great in containers and planters, either by themselves or mixed with other plants. They add excellent low-growing color and texture planted in a rock garden, draping down a retaining wall, or planted anywhere a cold and drought tolerant ground cover or trailing plant is needed. They can also be used as permanent additions to hanging baskets.
