Ack! I somehow did not realize that BLUEBIRD OF HAPPINESS had flared falls, and I bought it last summer!
Oh well... I bought it for the name and the color; hopefully the flare won't be so bad that the name/color/other plant traits can't make up for it.
I agree with you about strappy, floppy falls. I know that is a trait of the older historic irises and that many people love such, but I really can't see much of beauty in those oldies - not having seen the modern beauties that are available to us. (What the eye has seen, cannot be unseen, and the eye wants more of that, not less.) If there were particular cultivars with certain rare traits especially worth preserving, then yes, they might be garden worthy (or at least hybridizing worthy), but in general, not in my back yard.
