Nice list, Cynthia. I grow Silverado in France, zone 10a, and it's stunning - amazing when next to a stronger violet blue. I have Coffee Trader on the way from Australia right now (order from Tempo Two being delivered via the Netherlands and France, I've had notification that it's en route).
I've noticed that the DB seems to say for all irises that the max recommended zone is 9... Perhaps they don't mind a little 'push' into 10a. I have found that in France irises are quite happy to bloom in the shade or the sun; given how sandy our soil is there I'm delighted that they grow at all!
