I live 15 miles west of Phoenix. Last spring a friend gave me several blue iris plants that she had been growing for many, many years under a giant mulberry tree. I planted some under a huge Palo Verde tree and some under a pygmy date palm to see which would survive. As everyone knows, we had record high temps this summer (2023). It looked like the irises would not survive. The leaves shriveled up and browned and I trimmed them off. It's now December and all the plants have flushed beautiful new green straps! I'm anxious to see if they bloom this spring! I've never grown them before.
