Delosperma congestum L.Bolus
Gold Nugget Ice Plant
Delosperma congestum is an alpine succulent that forms a spreading carpet of semi-woody stems and glossy pale green leaves that change to a reddish or maroon color during winter. It grows up to 1 inch (2.5 cm) tall. Flowers are daisy-like, bright golden yellow, and appear densely above the foliage during summer.
USDA hardiness zones 5a to 10b: from −20 °F (−28.9 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Delospermas grow in USDA plant hardiness zones 5 to 9 and will bloom for most summer and fall. Their foliage is mostly evergreen, and because of this, they make a great year-round ground cover. However, while the plant is evergreen, it will often have some dieback of foliage in the winter.
These plants prefer full sun but can tolerate some light shade in the garden. Because they are succulents, they do not tolerate wet soil, though they do well in poor soils. Wet soil, especially during the winter months, is likely to kill the plants. However, this plant can become invasive in areas where the soil stays consistently dry, so it is best to consider this when planting it.
Delosperma 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.
