Ted, I think that one is "Monster White". It sure does grow and bloom like a monster.
I also have the yellow 'Charles Grimaldi' in a big pot in the pool cage. It makes nice shifting shade for a rack of orchids and likes getting misted every day along with them.
Then there is a collection of pink ones, some of which we're not sure of the names. (I've been trading cuttings, did you guess?) This one might be 'Isabella' and I have two paler pinks, 'Cherub' and 'Frosty'.
