LOL Dee. I am not real sure even that will help much. I tried to track down the name of one of mine that looks pretty close to that. Unless you have identical soil conditions, sunlight and so forth and don't think there is any way to be absolutely certain.
A wise iris woman (her name was either Dee or Polly) once said it is dangerous to attempt to ID from a photo.
It is very pretty Allison! I hope you can enjoy her without knowing her name.
