Adding to the discussion of mislabeled roses, I should say that I have bought roses from a million mail-order nurseries, many of which are now defunct. I've bought many, many roses from Northland Rosarium and never received a single mislabeled one. Some other nurseries that have never sold me mislabeled roses are Palatine, Regan, Garden Valley Ranch, K&M, Burlington, Rosemania, Edmunds, Wayside, Greenmantle, and S&W Greenhouse. I could add another 30 or 40 to this list, but those nurseries are now out of business or don't offer mail-order sales anymore.
Chamblee's sent me one mislabeled rose, but I've bought dozens and dozens of roses from Chamblee's, so that was an anomaly.
