This one was striking for the sharpness of the purple/white divide. I don't remember seeing that in any other Phalaenopsis. It's probably especially impressive when one gets a really big spike, with lots of individual flowers. There aren't a lot of phals I can imagine really wanting to own, but I wouldn't mind having one of these. (Or I-Hsin Balloon. I mean, if you want a list, I could come up with a list.)
Most years, I'm not impressed with the Phalaenopsis at the show, but I really liked most of the ones I got photos of this year. Whether this is because they're getting better, my standards are lowering, or I'm just not taking photos of the boring ones, I'm not sure, but if I had to guess, I'd guess the third option. I know there was at least one gigantic plain-white phal that I didn't bother taking a picture of.
