    Origin and Habitat: Crassula capensis is endemic to the Western Cape (near the coast from Clanwilliam and the Cape Peninsula in the west to around the southern Cape town of Riversdale in the east), South Africa.
    Habitat and Ecology: Fynbos. This species grows on gravelly slopes, usually exposed, even on Table Mountain where damp spots among the crags are seasonally plentiful, or in moist, sheltered places under overhanging rocks. The habitat of this species and the environment is characterised by a number of stress factors such as summer drought, low soil fertility and periodic fires. The fires have a frequency of 4 to 40 years and are a natural phenomenon in fynbos. Fire provides the major cues for germination in the wild and the tubers, not destroyed by the fire, prosper from winter rain. Nutrients obtained from the ashes and the removal of some large shrubs that previously dominated the space, contribute to the good life. Moreover it is stimulated by veld fires resulting in larger flowers. Flowers are produced from autumn to early summer. Crassula capensis is widespread and not in danger of extinction, but habitat loss to urban and agricultural expansion, as well as competition from alien invasive plants are potentially threats.

    Common Names include:
    ENGLISH: Cape snowdrop
    AFRIKAANS (Afrikaans): skaamblommetjie

    Description: The Cape snowdrop (Crassula capensis) is a tiny perennial geophyte with a delicate appearance and has two pairs of broad scarcely fleshy leaves close to the ground. It grows from a rhizome and several small tubers and may form small dense clumps through suckering. It is said that the plant reaches heights of 5-15 cm tall (20 cm in favourable conditions, although this is probably not often observed). Nodding, star-shaped flowers are borne in a terminal umbel, the peduncle 20-70 mm long.
    Stem. Erect 50-150(-200) mm high, sometimes branched from base.
    Rhizome: branched, with several globose tubers with fibrous adventitious roots.
    Leaves: In 2,3(4) pairs developing before or during flowering. Usually only lower ones with petioles up to 20(-30) mm long. Lamina scarcely fleshy, flattened, obovate or elliptic, (10-)20-60(-80) mm long, (5-)15-50(-60) mm wide, obtuse rarely bluntly acute, crenate or doubly crenate, rarely serrate to entire, surface glabrous, green, rarely purple below. Base cuneate to cordate.
    Inflorescence: Usually terminal, an umbellate to flat-topped thyrse, with peduncle 30-100(-130) mm long.
    Flowers: Nodding, star-shaped, to 2 cm in diameter, white, or tinged pink. Calyx lobes (sepals) triangular-lanceolate, l-2(-3) mm long, glabrous, slightly fleshy, green often tinged red. Corolla star-shaped, 5-7(-12)- merous, scarcely fused at base, white or tinged pink, lobes lanceolate, 3-6(-8) mm long, tip sharply acute, spreading. Stamens with brown anthers.
    Similar species: C. capensis is distinquished from Crassula saxifraga by its star-shaped flowers and by a few bracts subtending the branches of the subumbellate inflorescence.
