How hardy is delosperma?
Native to eastern and southern Africa, Delosperma thrives in heat, is drought tolerant and virtually maintenance free when given the right growing conditions. Also known as ice plant, this hardy perennial is named for the shimmering quality of the flowers and foliage that resembles ice crystals. Ice plants are low-maintenance perennials that mostly thrive on neglect. Delosperma is not prone to many diseases, but downy mildew, leaf spot, and rust are common problems. Early detection and prevention are essential to keeping ice plants healthy and thriving.Delosperma has strong roots that take hold of dry soil and build a dense mat of succulent foliage that anchors to the ground. Because its root system is fast to spread and take hold, ice plants can effectively stabilize the ground and prevent erosion alongside slopes, hillsides, and coastal areas.Ice plant is not good erosion control- In fact, Ice plant can actually contribute to soil destabilization and erosion. Most ice plant roots are shallow, 3 to 6 inches deep.

Does Delosperma like sun or shade?
Delosperma grows best in full sun and well-draining soil, preferring sandy or gravelly ground that doesn’t hold water. Once established, these plants handle drought well but cannot tolerate soggy conditions, with excess winter moisture being their biggest threat. Delosperma needs nitrogen, phosphorus, and potassium for optimal growth and blooming. Fertilize in early spring and mid-summer for best results and vibrant flowers. Monitor for signs of deficiency or over-fertilization to maintain plant health.Temperature: Hardy in USDA zones 5-10, Delosperma is adaptable to various temperatures but prefers warm climates. It can withstand mild frost but may suffer damage in severe winter conditions. In colder regions, ensuring well-drained soil and using mulch can help protect the plant’s roots during winter.Water them regularly (weekly) during the heat of the summer, as Delosperma come from areas of South Africa that get summer rains. But keep them dry over the winter months.
Is Delosperma invasive?
The ice plant is native to South Africa’s coast and is considered invasive in coastal California and northern Mexico. It has been shown to spread rapidly and easily choke out native plants along the coast north of Humboldt County to Baja California. However, it is not considered invasive in other areas. Ice plants are used in sunny but sheltered desert gardens, in rock gardens, on slopes, or as ground cover or edging plants. Individual plants often spread around 2 feet, though they occasionally can spread even more than that.
