A well known species in cultivation, but also widely distributed in nature (from southern Namibia to the Eastern Cape).
What is not so well known yet is the genus name Curio which apparently we are now supposed to use. So beware, when the taxonomy police comes round next time, you will need a good excuse if you still use the name Senecio (or even Kleinia) radicans.
Whatever you want to call it, I hope you will enjoy the following pictures.
