Hello, I have bought this plant at the belgian national botanical garden in Meise more than ten years ago. I think the species comes from South Africa and was sold in order to spread it because it was endangered. I'd like to know more about it in order to, among other things, improve its conditions, give it a bigger container with the right substrate. The plant doesn't seem to ever produce flowers or fruits. What is shown on the picture is around 20 x 20 cm (7.8 x 7.8 inches). Thank you in advance.
