GreenIris said: There are many Irises that do last. It's just some are weak or too weak for a particular climate. I have been growing them for 12 years now and have had very few die on me. Some don't bloom that often though. And I do have some that have never bloomed

I agree. I've only had a couple that actually just died on me. I've had some that increased but didn't bloom, and some that increased, then bloomed, then kept increasing but didn't bloom again. There doesn't seem to be any correlation between the poor performers and hybridizers, either. I thought maybe the irises bred in the PNW didn't like my drier, hotter conditions, but no. Most do great, some don't. It's a mystery!
