Pickle Plant, Ice Plant
Drosanthemum pruinosum, Mesembryanthemum echinatum
Delosperma echinatum is a shrubby succulent with slender stems that bear pairs of bright green leaves with soft white spines. The stems are upright or trailing, forming a mat or an up to 18 inches (45 cm) tall shrub. Leaves are thick, fleshy, and up to 1 inch (2.5 cm) long.
Flowers are white, pale yellow, or yellow and appear at the tip of the stems from late winter through fall, with a peak in spring. They are up to 0.8 inches (2 cm) in diameter.
Delosperma echinatum is native to South Africa (Eastern Cape).
USDA hardiness zones 7a to 10b: from 0 °F (−17.8 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Delosperma plants grow in USDA plant hardiness zones 5 to 9 and will bloom for most of 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. In fact, 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.
