The flowers of Crassula cultrata grow in densely clustered thyrse-shaped heads spread along the erect long stalks. The petals have narrow sides and rounded tips; fiddle-shaped or panduriform. The flowers are small. They have 5 mm long tubular corollas formed by the creamy white petals.
In bud the flowers appear yellowish green, however, when only the fleshy and hairy, triangular sepals, ciliate on the edges, are visible. Blooming happens late spring to midsummer (Vlok and Schutte-Vlok, 2010; JSTOR).
The flowers in picture are not yet open. The photo was taken in Meiringspoort in January.
