Tecomaria capensis is almost always a scrambling shrub, rarely a tree (SA Tree List No. 673.1). The plant is found on the South African south and east coasts as well as in parts of the Lowveld and Mozambique. The capensis specific adjective stems from the first description of the plant, at the time associated with the southern end of the distribution.
The species was found to escape and slightly invade bushveld in the Magaliesberg. This yellow flowering form of the plant was seen in a Gauteng garden. Foliage is as dense and lush as seen here unless the plant suffers drought stress.
There is a related genus called Tecoma comprising some South American species, distinguished from the about 5 African Tecomaria species. T. capensis is, however, still sometimes called Tecoma capensis. The two genera are no longer believed to share a common ancestor. Only T. capensis grows naturally in southern Africa (Coates Palgrave, 2002; Riley, 1963; Letty, 1962).
