‘Jewel of Desert Grenade’
Delosperma cooperi (Hook.f.) L.Bolus is the correct and accepted name for the Ice Plant. It was described as such by Harriet Margaret Louisa Bolus in Flowering Plants of South Africa in 1927. It was first described as Mesembryanthemum cooperi by Joseph Dalton Hooker in the Botanical Magazine in 1877.
Joseph Dalton Hooker (Hook.f) was a 19th-century British botanist and is considered the founder of geographical botany. He was Charles Darwin’s closest friend. He served as the director of the Royal Botanical Garden at Kew for 20 years, succeeding his father, William Jackson Hooker (Hook.).
The genus, Delosperma N.E.Br., was named and described by Nicholas Edward Brown in Gardener’s Chronicle in 1925.
Plants of the World Online by Kew lists 170 species in the Delosperma genus (as of 8-5-21 when this page was last updated). It is a member of the plant family Aizoaceae with 120 genera. Those numbers could change as updates are made by POWO.
Delosperma cooperi, commonly known as Ice Plant, is native to South Africa. They can form a vigorous growing ground cover if they like their conditions. Although they are considered evergreen, in cooler parts semi-evergreen is most likely. They like it dry most of the time which is likely why they don’t survive in areas with cooler, wet winters.

It seemed to have its ups and downs for some reason but it still flowered pretty well. I had moved the potted plants to the back and front porches on July 4 because of a Japanese Beetle invasion in the other area. I put the Ice Plant on the back porch in full sun and it seemed to do better.
Here, in the above photo, it was looking much better…
The above photo was taken late in the afternoon and its flowers had closed up for the day. I took this photo the day I moved the plants inside for the winter. I moved it inside, too, but after a while it fizzled out.
