If the picture looks a bit, well, dated–it is. Scanned from a transparency taken in January of 1994 on top of Platberg, a Nature preserve on the slopes above Harrismith in the Orange Free State. This was taken on my very first foray in the Drakensberg area with Dr. J.P. Roux, now deceased, who had created the Drakensberg Botanic Garden in the town below a decade or more earlier. The Delosperma grew wild on the site of that Garden as well. I have subsequently seen this many places in the Drakensberg proper–although I haven’t scanned slides of it from those areas yet. It is well established in cultivation, including some wonderful color forms, see below.
