Gerrardanthus macrorhizus 'Bigfoot' is native to lowland forests of South Africa (Eastern Cape and KwaZulu-Natal) and Eswatini. The specific epithet macrorhizus means "large-rooted, having large root" and refers to the large tuberous rootstock of the species. 

A perennial climber with woody stems that arise from the flattened tuberous rootstock. The smooth, shiny, dark green leaves are prominently veined and somewhat succulent, and can measure up to 3.2 inches long and wide at maturity. These have been grown in a shade house, can be acclimated to direct sunlight, but the caudex should stay in the shade. If grown outdoors, place 'Bigfoot' under a shelter to keep it out of the rain and bring it inside when it gets too cold. Requires excellent drainage. This is a very hardy plant once established, will survive temps from 30F to 95F, and prolonged periods of drought.
