Crassula sarcocaulis

Succulent perennial of the Crassulaceae family, this species is native to the mountains of South Africa and Lesotho, where it grows on the rocky slopes and granite outcrops of the Drakensberg, between 1,800 and 3,000 meters in altitude. It endures cold winters with regular frosts, making it one of the few hardy crassulas suitable for rock gardens in our climates.

It forms a small bushy and woody sub-shrub at the base, 15 to 30 cm in height, with branched and tortuous stems, brown to reddish, giving it a miniature appearance reminiscent of a natural bonsai. The leaves are small, fleshy, oval, medium green to green-red depending on sunlight and season, arranged in opposite pairs along the stems.

The flowers, tiny and star-shaped, are a soft pink to pale pink, grouped in small dense terminal cymes that generously cover the ends of the branches at the time of flowering.

In its natural habitat, its flowering extends from December to February, during the austral summer. In cultivation under our latitudes, it blooms from July to September.

In cultivation, it requires full sun, a very well-drained, poor and mineral soil, with good protection against winter moisture. It is suitable for rock gardens, walls and trough cultures. Its hardiness reaches about -12 to -15 °C in dry conditions.
