Amazing looking plant and very nice flowers! It's also on my list but can't find any vendor that has it in flowering size in Europe. All i can find is young plants aswell. I'm guessing you bought this beauty from an American vendor?
After looking at your beautiful plant, I went to look at my plant which is about 4 years old, healthy looking, but has never bloomed. Thanx for posting, now I have something to look forward to.
