The $7 catalog with 9000 iris is probably Riverview Gardens. It does NOT contain pictures: it is a hefty listing of the varieties they grow. To my knowledge no one else offers a "full color" catalog, but Sutton's catalog has color pictures, as does Mid-America, Aitken's Salmon Creek, Keith Keppel and Contemporary Gardens (Contemporary did not put one out this year). There are probably a few more but that should get you started.

I am looking for Iris catalogs with photos in them. I did find this but it appears most do not have photos in them. I know about Schreiner's, Cooleys and Marycotts. there is another one that costs $7 I cannot find or remember who it was. They said they had 9000 types of iris but did not tell me how many pages or photos in catalog. I thought this was very high. Does anyone know of others? I found this link but it doesn't tell me much.
