My favorite bicolor is one I haven't seen bloom, Floyd Boatwright's "Deeds Not Words".
I really admired the picture a few years ago, and finally have it, but I'm pretty sure it won't bloom until next year. I was apprehensive, because as far as I can tell, there is only one image of it in circulation, even though it was introduced about 5 years ago. Not usually a good sign.
Hopefully it's an improved, more strongly bicolored Malaysian Marketplace.
