I'm really glad to see this posted. Ditto for those Brock posted including the Sibs (and his great links leading to more). I wonder if Barbara Null is still having luck with the Pacific Coast irises she grew from seeds and seemed to be doing well in Texas. Folks are always referring to the book 'The World of Irises' and photos of the non-bearded ones and old diploids (thanks T. Silvers)and some that may be more obscure in the bearded groups are a great way to illustrate how wide that world really is.
