Not really
. Could be the grower. Generally I do better with getting arilbreds to match the official registration specs, but not so much other bearded iris. Mostly the medians just haven't survived well and those that have don't bloom very often. IBs have performed the best. The medians tend to do better after a colder and wetter than normal winter. Often our winters don't provide those conditions. TBs do pretty well a lot of the time, but just tend to be shorter and with fewer buds than they have for others. Spuria iris reach good height most of the time. I used to spend a lot of time trying to figure out why the TBs didn't do those things very often, but I gave up finally and just take what I can get.
