A fully developed Crassula multicava inflorescence is rounded or elliptic on a peduncle of about 8 cm. Structurally the inflorescence is thyrse-shaped, the individual flowers star-shaped, growing two per node. The flower pedicel is from 3 mm to 8 mm long.
The five sepals are triangular, up to 2 mm long, hairless and sometimes red. The five (sometimes four) petals are fused at the base, also triangular, up to 4 mm long. The corolla is white or cream, sometimes tinged red at the tips, the anthers purple. Flowering in the natural habitat happens in winter and in spring, the season sometimes shorter.
The erect fruit follicles bear from 12 to 20 ellipsoid seeds each. After flowering the plant often grows new plantlets or brood-buds vegetatively from the axils where the flowers had been (Pooley, 1998; www.llifle.com).
