I can understand Shawn's concern about possible unwanted substitutions. I always specify "No Substitutions." Nevertheless, two different iris nurseries have sent me substitutions, mislabeling them as what I had ordered because they apparently didn't want to issue refunds for what they didn't have. I won't say which nurseries they were, but never again will I place orders with those two nurseries. The flower bed was one I had never before planted with iris, and I put labeled markers in with them when I planted them, so there was no mistaking what they had done when they bloomed the following spring.
However, with these experiences behind me, I now order early in the year, and, if the nursery asks for a preferred shipping time, specify the earliest possible shipping date, figuring they are less likely to be out of what I want.
I have to say that I have never had trouble with Schreiner's making unwanted substitutions.
