Crassula tetragona is doing very well here in the Addo Elephant National Park.
Many erect stems that branch high and low contribute to this dense green and grey-green stand. The photo was taken in August, well before the plant’s summer bloomtime. Flourishing plants may reach 1 m in height, although this may not include all six of the recognised subspecies.
A subspecies expected to be found at Addo is C. tetragona subsp. robusta, commonly growing in the river valleys of the Eastern Cape (Frandsen, 2017; Vlok and Schutte-Vlok, 2015; iNaturalist; iSpot).
