Nice plant! :)
Very nice Alain. Of the mesembs, I think Lapidaria looks the most like a sculpture. The leaves look as though they have been chiseled from pieces of stone. Your first two photo show this beautifully. Is this a large single plant, or a collection of plants? Which ever, it's beautiful.
It is one plant. In the past I have let the dead flowers get stuck on the leaves which spoils the look of the sculpture.
