Ice Plant (Delosperma Congestum) – What a carefree yet gorgeous ground cover plant! Excellent for containers or rock gardens, grow Ice Plant from ground cover seeds and watch it thrive! This Ice Plant is marked by succulent apple green foliage and brilliant yellow flowers that open in the morning and close in the late afternoon. Delosperma Ice Plant makes a low growing mat that makes the perfect ground cover carpet for dry, sunny areas. This Ice Plant is native to the high altitudes of eastern South Africa, somewhere between an alpine and high desert habitat, so you know it can take the heat and sun in your garden. For a fast growing ground cover plant that beautifully softens edges, flows down slopes, and grows in pockets of rock walls, start Ice Plant seeds and reap the rewards!
Sow Ice Plant seeds indoors 4 – 6 weeks before last frost is predicted. Use starter trays and sterile potting mix. Press Ice Plant ground cover seeds into the soil but do not cover the seeds. Keep the seeds moist but not saturated until germination occurs. Transplant outdoors, 10 inches a part when temperatures are warmed. Find a sunny location with sandy, sharp-draining soil. In the hottest climates, Ice Plant would do well with some afternoon shade. Care of Ice Plant includes cutting off old, dead stems and spent flowers at any time of the year to tidy the plant.

Mesembryanthemum nubigenum (basionym)

USDA hardiness zone 5a to 10b: from −20 °F (−28.9 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Delosperma plants grow in USDA plant hardiness zones 5-9 and will bloom for most of the summer and fall. Their foliage is mostly evergreen and because of this, they make a great year-round ground cover. While the plant is evergreen, it will often have some dieback of foliage in the winter.
Delospermas prefer full sun but can tolerate some light shade in the garden. Because Delosperma are succulents, they do not tolerate wet soil, though they do well in poor soils. In fact, wet soil, especially during the winter months, is likely to kill the plants. In areas where the soil stays consistently dry, this plant can become invasive, so it is best to take this into consideration when planting it.
The Ice Plant can be propagated by division, cuttings or seeds. If propagating by division, it is best to divide the plants in the spring. Cuttings can be taken anytime in the spring, summer or fall. When grown by seeds, scatter the seeds on the surface of the soil and do not cover them, as they need light to germinate… – See more at: How to Grow and Care for Delosperma

Information About the Hardy Ice Plant
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 tall and 2 to 4 feet wide.
Ice plant flowers grow in USDA plant hardiness zones 5-9 and will bloom for most of the
summer and fall. Their foliage is mostly evergreen and, because of this, they make a great year-round ground cover. While the plant is evergreen, it will often have some dieback of foliage in the winter.
Some popular varieties of ice plants include:
- Cooper’s ice plant (Delosperma cooperi) – This purple ice plant is the most common variety
- Hardy yellow (Delosperma brunnthaleri) – This species consists of lovely yellow flowers
- Starburst (Delosperma floribundum) – An ice plant variety with pink flowers and a white center
- Hardy white (Delosperma herbeau) – A white-flowered type that offers exceptional beauty
