Thanks for the info Null. You live and learn, if you keep your mind, ears and eyes open and your mouth shut. I'd be interested to see how the fruits are in comaprison from these more colorful flowers. All of the dragon fruit that are sold for production of fruit that I have seen have all been white in blossom color. That would include (in my experience) Physical Graffiti, Purple Haze, American Beuty, Yellow, Dark Star, Delight, Cosmic Charley, Vietnamese Jaina and Haley's Comet
