"That's All Folks" grows well for me in N. AZ also.
It's really a bright and cheerful iris.
Glad to see your pictures again, as always.
You certainly set the standards to aim for in picture taking.
Someday I might get there.
With all the moisture we've been getting, I've really had to clear
any debris around the rhizomes here, rot is something I usually don't
have to make an effort to prevent.
And so far, we've really not had
consistent cold days, just some cold nights but nothing drastic.
Mother nature usually does a trick in Apr. like snow. We'll see.
