RED ALDER | Rooiels | Cunonia Capensis
The Tree
Rooiels does not grow well in very hot and dry or windy conditions, preferring a more temperate climate. It is common in the Southern Cape with abundant populations around Knysna. It may be seen in forests and moist areas, especially along watercourses. It is found along the coast and adjacent inland areas from the Western Cape eastwards to Mozambique. In forests it may reach up to 10m in height but out in the open it may only reach 5m.
The bark is rough and dark in older specimens. Small round pustules (cork patches) are sometimes found on the bark, resembling ostrich skin. The young stems are pinkish red. It bears small white to cream-coloured flowers borne on long, dense spikes.
