I ordered from them last year and everything grew nicely. I don't think any of them bloomed this past spring (maybe one of the SDB's), so I can't attest to the accuracy yet.
So far, I've never received a mislabeled iris (that I know of) from: Superstition, Napa, Bay View, Exline, Bluebird, Iris City, & Mid-America..
I have received mislabeled iris from: Schreiners, Blue J, and Iris Patch (out of business now). Schreiners is good about replacing anything that's mislabeled, even years down the road.
