Thanks, Janet. Your link
http://crassulaceae.net/xGrapt...... is great and I've been browsing through it.
The closest I could find were xGraptosedum ‘Mediterranean Mystery’ and xGraptosedum ‘Ghosty’. What do you think? As you say, it's far from easy...
When I come back in a couple of weeks I'll try to get to two great local gardens, the Jardins des Serres de la Madone, (almost our neighbour here) and Hanbury Gardens in Ventimiglia, just over the Italian border, to see if anyone there has an idea.
And I'll bring my DSLR!
