The flowers of Crassula lactea grow in a stem-tip cluster of about 10 cm long above the leaf rosette. The usually white flowers are star-shaped, each with five pointed petals. Off-white flowers are sometimes seen, also red-tinged ones. The narrow petals are about 8 mm long.

Five straight, white filaments spread around the flower centre. Alternating with them five broad-based carpels are topped with outcurved styles ending in tiny stigmas.

Flowering happens in late autumn and most of winter. The photo was taken in May (Frandsen, 2017; Smith, et al, 2017; Bond and Goldblatt, 1984; iNaturalist).
