ICE PLANT

We've had 3 or 4 of these small green plants in a big pot in the greenhouse but not doing very much. Very suddenly one of them has produced a couple of flowers and the others look as if they're about to. Just went back only 15 minutes later and the flowers have closed up - perhaps the sun has moved slightly. Mrs P has producd her catalogue and they're called Delosperma and looking at the picture they should produce lots of flowers so I may need to reblip another day. Originally from South Africa.
