Delosperma ashtonii

Succulent perennial of the Aizoaceae family, native to South Africa, where it grows in the rocky and arid areas of Lesotho and the highlands of the Drakensberg, at altitudes exceeding 2,000 meters. This mountainous origin gives it a hardiness superior to that of many other Delosperma.

It forms a low and dense mat, 5 to 10 cm in height, with creeping and branched stems bearing fleshy, cylindrical leaves of a glaucous green, covered with tiny shiny papillae characteristic of the family. This evergreen foliage maintains a neat and compact appearance in all seasons.

The flowers, solitary and very numerous, have fine petaloid strips of bright magenta-pink with satin-like reflections, with a creamy white center creating a sharp contrast. In its natural habitat, its flowering extends from November to January, corresponding to the southern summer. In cultivation in the northern hemisphere, it mainly blooms from June to September, sometimes longer.

In cultivation, it requires perfect drainage, a poor mineral substrate, and full sun exposure. It tolerates moderate to severe frosts provided the soil is dry in winter. It is suitable for rock gardens, walls, and sunny borders where it quickly covers the ground.
