@alilyfan,
I started with blue flag iris from a friend and then gotten a few more irises through trades. I don't have a 'iris bed' like many of the serious iris growers (but hopefully one day very soon); I've been placing them wherever there's a spot available. I've not been a good iris grower...losing many of them. Some have never bloom.
There was a white historical iris - the trader said it was from old cemetery - it was lovely but haven't seen it for 2 years.
Many I transplanted to our new home and they didn't make it. (Probably need to update my listing)
A friend and I ordered some iris a few years back from a group sale - those we are trying to save (she had it in a very dry baked soil and they were left defending themselves). Anyway, I would like to keep these happy. Been reading up on iris growing. Thanks for your help.
