Description: Delosperma echinatumSN|26454]]SN|26454]], also known as the Pickle plant, is a type of ice plant, native to South Africa. It has odd looking succulent leaves with bristly hairs on small, thin wiry spiny stalks. Leaves themselves are also spiny (but not dangerously so). The most notable features are the water vesicles that cover the leaves.
Habit: It is a small perennial succulent shrub which has a more upright habit than most Delospermas, often reaching 45 cm in height when grown outdoors (usually less than 30 cm tall when grown in containers or baskets).
Roots: It has deep succulent roots.
Leaves: Up to 2,5 cm long, light green covered by water vesicles.
Flowers: Small white, pale greenish-yellow or yellow, up to 2 cm in diameter at the tips of stems.
Blooming Time: Spring.

Cultivation and Propagation: Delosperma echinatumSN|26454]]SN|26454]] is one of the more easily cultivated succulent species. It is also surprisingly hardy outdoors. It's tolerant of wet and cold and can tolerate less than perfect drainage, but it will suffer under prolonged water stagnation, and thus prefers well drained soils, or even rocky terrain. Excellent potted plant.
Growth rate: It grows fast, needs to be contained or it becomes invasive, and also like to self seed everywhere. If not checked it could take over entire areas of garden, and even escape into the wild.
Soil: It prefers deep, well-drained, lean, sandy, or rocky soils. The soil mixture should be slightly acidic, with a pH of 6.5 to 6.0.
Fertilization: They should be fertilized only once during this period with a very dilute fertilizer. We usually dilute the fertilizer to ¼ the recommended rate.
Watering: Water moderately from early spring to the end of autumn (plants should be allowed to dry in-between waterings), and keep the compost quite dry when the plants are dormant watering, only if the plant starts shrivelling (, but they will generally grow even in winter if given water). Disliking overly wet conditions, it is best to also cover it with an anchored sheet of plastic during the winter if climate is particularly wet and cold. During wet seasons allow air circulation.
Exposure: It need full sun to light shade. In full sun it is more compact than in shade.
Hardiness: It is tolerant of both heat and cold and is hardy from zones 7 through 10. In areas prone to very intense frosts, grow in an intermediate greenhouse or conservatory, in pots of cactus compost, obtainable from good garden centres. When grown outside in zone 7, it should be treated as an annual.
Propagation: Delosperma echinatumSN|26454]]SN|26454]] is easily propagated from stem cutting or by seed. Seed readily germinate at 12 to 18° C.
