How to Grow and Care
Tavaresias are mainly grown by plant collectors, lovers of succulents, and enthusiasts who enjoy growing unorthodox-looking plants. They come from summer rainfall areas and are intolerant of excess water, humidity, low winter temperatures, and easily destroyed molds. Flower buds drop off easily in response to the slightest touch or unfavorable conditions. Tavaresias prefer light shade rather than full sun, although stems may not color up under shady conditions. Тhese succulents grow well in light gritty soil with very liberal drainage.
Plants are usually increased by cuttings, which, as they are very succulent, should be allowed to dry a week after they are taken off, when they may once be put singly into pots. Grafting the Tavaresia on Stapelias is often useful and can be recommended.
