Probably the most ,by any "one" hybridizer, in my collection....although, I guess there are "several" different "Schrieners" involved, so I suppose if all the Sass family was lumped together...there might be more of those....anyway, it IS a pretty good bunch ! I have several of the older Schriener iris on my "long term " wishlist, but it's very doubtful they even exist anymore, at least , no one seems to have them.
