Ursula, thank you! No wonder I couldn't find it!!! Looking at it again (I had seen a photograph of I a long time ago and wrote the name down) it reminds me of the Cattlianthe Confetti that I have in sheath now.
I had to look up C. Jacqueline Kennedy and I can't believe th price, especially when there are other flowers that are just as pretty. I would e afraid to buy such an expensive plant, I'd probably knock it off the windowsill or the cat would eat it or something like that.
