I've had good luck with Wild's, also.....We've bought more "other types" of plants, than iris....but, everything has grown, and seems, as MaryAnn said, 'true to name"....the iris I have bought there have always arrived "potted", and really seem to 'take off' well
I COULD tell a real horror story about Breck's, and also Springhill......but I think you have already heard enough !
