Crassula arborescens flowers

The white Crassula arborescens flowers spread their five narrow, acutely pointed and almost straight to slightly out-curving petals around the flower centres. Corolla diameter is about 1 cm.

Tall thin filaments of the stamens angle out, tipped by tiny, whitish anthers. Inside the stamens the five stubby carpels in which the seeds grow form a third floral ring of vital parts. There are also nectar glands known as squamae in a (here) invisible ring at the base of the carpels.

Protraction of the floral sequence is illustrated in the inflorescence by old flowers turning brown first in petal centres, while creamy, pointed buds still prepare to open among them. Abrupt changes in inflorescence branch thickness occur, down to the thin pedicels of individual flowers.

Flowering happens in spring and summer (Vlok and Schutte-Vlok, 2015; iNaturalist).
