I have many new blended iris (mostly Burseens) that will bloom, hopefully, for the first time in the spring. This thread made me realize how few I had before this year.
My favorite blend is Inner Space:
My close second is Zlatovlaska (and as Mary Ann said - bonus points for being a SA!):
And love the blend on what Bruce Filardi sent me as So Unusual, though I think it may be the parent American Maid instead:
Touch of Mahogany was a lovely bunch. Think it bloomed itself out though.
And I agree on Trillion!

Praetorian Guard in the background is a bit of a blend too I realize.
