Etymology
The specific epithet "barklyi" (pronounced "BARK-lee") honors Sir Henry Barkly (1815-1898), a British politician, colonial governor, and patron of the sciences, who collected specimens of this species in 1871.
Origin
Tavaresia barklyi is native to South Africa, Angola, Botswana, Namibia, and Zimbabwe.
Description
Tavaresia barklyi is a succulent plant with erect blue-green stems covered with tubercles tipped with three sharp bristles. The stems are cylindrical with 10 to 12 ribs and can grow up to 2.4 inches (6 cm) tall and 0.6 inches (1.5 cm) in diameter.
During the summer, Tavaresia barklyi produces showy, tubular to trumpet-shaped flowers that can reach a length of 4.4 inches (11 cm) and a diameter of 1 inch (2.5 cm). The flowers arise at the base of the stems. They can be pale yellow, yellowish-pink, or cream-colored, with dark red spots and streaks on the outside, darker on the inside, and almost fully maroon to purple at the base inside. The fruits consist of a pair of elongated follicles that, when fully mature, burst open to release seeds, each with a tuft of hair.
Hardiness
USDA hardiness zones 11a to 11b: from 40°F (4.4°C) to 50°F (10°C).
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 for 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.
