Crassula congesta

A small succulent from the southern Cape of South Africa, recorded mainly in the Little Karoo and nearby Western Cape. Field observation notes on GBIF record plants on quartz patches and recovering after rain, and one observer suspected they die after flowering. No climate was measured, so the conditions come from nearby Little Karoo sites and genus knowledge.

Where it grows wild

Records place it in the arid Little Karoo and surrounding Western Cape, including a quartz patch near Anysberg Nature Reserve. It grows low among stones in open succulent karoo vegetation.

Few records carry an elevation; the Little Karoo sites nearby lie around 300–900 m.
