I've certainly seen references to them growing in parts of Arizona, Usha. If you bought it from a good local nursery, that is a good sign the plant should grow where you are. How much water is it getting?
I have mulched it well. I was watering it twice a day, but now decided to water it on alternate days. It rained here yesterday. So I have ti watch how it does with the alternate day feeding.
I can't imagine that a plant in shade needs watering twice a day, Usha. The best thing to do is to stick your finger in the ground a few times to get a sense for how quickly your soil really dries out.
I am cutting down the water. Thanks, Douglas.
