Over the years I've ordered from several vendors including Superstition, Mid-America, Schreiner and others. Mid-America & Superstition have always been good with their packaging, quality rhizomes and customer service. I would even say "above average". I was disappointed with my last order from Schreiner (2018) because of rhizome quality.
Sutton's quality and service is IMHO "excellent". The last order from them came with large healthy rhizomes, roomy packing and a couple of bonus irises. In all there were 12 large rhizomes nicely packed in an over-sized box; all correctly labeled. Below are some photos of this order. I do not usually photograph orders, but this one impressed me.
Box arrival; no damage
Well packed and clean
