Why the raised bed, Elm? I ask because I moved an AB from a more
protected, sandy site last year, into my raised nursery bed, and it bloomed for
the first time in 6 years. I also got 4 AB's last year, and 3 of them
bloomed; all in the nursery bed as well. Should I just leave them there
instead of moving them out into the landscape?

Yes, the + after an OGB means that the iris has a
high amount of aril blood. Even here in my climate, in a raised
bed, some of the OGB+ varieties are not reliably hardy. It depends on
whether the greater amount of aril blood is oncocyclus or regelia (regelia is
hardier). The - designates that there is but a quarter aril blood in the
mix. Of the two iris you pictured (nice photos!), Omar's Gold and
Persian Sapphire, both of these have SDBs in their backgrounds, and that makes
them hardier, in my estimation. The fact that you grow them in a raised
bed has a lot to do with your success.
