Welcome. Amerillo will sure stress test any Bearded Iris you get. You might want to consider a few really tough varieties at first. We live in KC and Titan's Glory, Dusky Challenger, Darcy's Choice and Premier Edition have done well for us.
I am sure we could send you a few to get you started. It would only cost you postage. And the rhizomes would be fairly large as they have been in the ground three years. Just remind us around June. All we ask is a report in a few years on how they are doing. I spent the Winter of 1963 at Amerillo AFB, by far the meanest winter I have ever been in. I remember an old addage about the wind, went something like this. Get a six foot length piece of telephone pole. Stick it in the ground and hang a heavy duty chain from it. When the chain gets to flapping around so bad that links break off, you know tomorrow is going to be windy.
Blessings
