If you don't mind smaller flowers, then, there are things like gardineri and its hybrids.
I have one such hybrid where one parent is Cascade Creek (Prince Edward of York x anitum) and the other is gardineri. My particular clone is exactly the size of gardineri I had in the plast. It is packing 6-7 growths in 4inch pot. It has bloomed 4 times in the last five years. So, a good bloomer and a robust grower.
