Flowers of Crassula capitella subsp thyrsiflora, growing in the Robertson KarooThe "campfire" cultivarCompact form of Crassula capitella subsp thyrsiflora
An extremely variable species. The narrow, pointed, splayed ("propeller-like"[2]) leaves are initially a light green, but become a strong reddish colour in the sun.[3]
The leaves are stacked, and near the base of the rosette they are larger. Near the top of a rosette, the leaves gradually get smaller and change into floral bracts, as the stem forms a long, pointed inflorescence.[4]
It is a small, succulent herb (15-40 cm in height) - with stems that are either erect or rambling and mat-forming. Each stem forms roots at its internodes, which take root if the stem lies against the ground.
C.capitella is mostly biennial, blooming in the summer, with small, white, star-shaped flowers forming all around each thick, upright stem.
[1][5]
It grows to a height of about 6 inches tall, and will be damaged when exposed to temperatures below 30°F (−1°C).[5]
Cultivation
Crassula capitella prefer full sun to partial shade, average watering needs, and shouldn't be exposed to temperatures below 30°F (−1°C).[5][6] It may suffer from foliage edema, which may be the result of rapid changes in moisture.[5]
Distribution
Crassula capitella is native to southern Africa; it is found in Transvaal, Free State, Eastern Cape, and in some parts of southern Namibia and Botswana.[1]
