I second Burgards. I wish she had more than tall bearded iris, but she is great to work with!
I also recommend Stout's, Blue J, Napa, Iris Sisters, Mt. Pleasant Iris Farm, International and Wild Iris Rows. I really like Schreiner's too but I have had one wrong iris out of each of my last 3 orders. I would say the digging crew isn't doing well with their labeling.
