Schreiner's is the largest iris hybridizer nd grower in the country, probably the world. Their acres and acres of iris fields are in several locations near Salem, OR. When you order from them you pay top dollar for several reason. First, no one has a larger selection and if you are looking for a particular award winner or older introduction (they carry few historic cultivars) the usually have it. The rhizome is among the largest and highest quality available. Their packaging is fancy with most rhizomes a full color picture label is attached. This is my third order and I have not been disappointed until now.
The cut area, where the rhizome is separated from the parent is usually clean and sealed. As you can see below, mildew formed on this area in many of the rhizomes in this shipment. I met the UPS driver at the street, so if these were sitting around in some damp place it was not on my porch. They will probably be fine, but I will let Schreiner's know.
