The colour of this Crassula alba var. alba inflorescence is more familiar to South African viewers than the Lowveld white ones also shown in this Album. Quite ironic as the word alba suggests white flowers!
The small flowers are closely clustered and flat-topped. Various floral stages are in evidence. The inflorescence size is variable, usually around 10 cm in diameter.
Flowering happens from midsummer to autumn. This photo is from mid-February in grassland near Balfour (Van Wyk and Malan, 1997; Germishuizen and Fabian, 1982; iSpot).
