There are many I haven't ordered from that I've heard good things about..
My favorites are:
Superstition, Napa Iris, Sisters Iris, Mid-America, Bluebird Haven.
I've also received nice Iris from:
Exline, & Iris city
There are a couple that I'm not inclined to order from again based on the number of wrongly named rhizomes I've received. Other folks have had good luck with them, but that wasn't my experience.
