About Tavaresia barklyi

Tavaresia barklyi · also called Barkly's tavaresia, trumpet flower stapeliad · houseplant

Tavaresia barklyi is a small southern African stapeliad succulent with soft-spined, many-angled green stems and large, pale-yellow, red-speckled trumpet flowers among the longest of any stapeliad. A choice but rot-prone collector's plant, it needs warmth, bright light, very gritty soil and minimal water. It is often grafted to keep it alive long-term in cultivation.

Preferred mix: Extremely free-draining mineral mix

Watch for — Rot-prone on own roots: Ungrafted plants collapse easily from rot. Keep dry, warm and very well drained, and many growers graft onto Ceropegia or Stapelia stock for longevity.
