Lovely, lovely, lovely! 😍😍😍
I have just acquired two C. Rex, and if they bloom just anything like yours, I will, indeed, count myself a very happy man!
This species, though, were quite difficult to find here on the other side of the Atlantic divide - I even had a couple of friends scout for me at the Easter Expo in Dresden (Dresdner Ostern). They bought a couple of very nice Paphs for me (among which were a Paph. sangii var. ayubianum, which, I think, it would be difficult to characterize, as your everyday grist of the mill plant), but they didn't succeed in tracing just one single Catt. rex.
I've now bought a 'selected cultivar' from a Catt-dealer, recommended by David (Monocotman), and I certainly paid for it. Many a time, I had regrets before I received the plant. When the plant arrived, the sender had, as an extra, added another C. rex, of more "plain" lineage - this plant was larger and much more well estsblished. My moaning ceased immediately - and now I'm just holding my breath while I test: 1) whether I can keep this species alive and growing, and 2) whether I will be able to make it flower!
