This is a short note to tell you I've seen jacarandas in neighborhood where I live, east of U of A campus. You may have seen information in link below but it's a good sign that U of A Pima County Cooperative Extension recommend it for Xeriscape in Tucson. Good luck with your landscaping project.

Here is a link that might be useful: Jacaranda mimosifolia

Thanks for the response! We'll hopefully be able to give it a try; waiting for HOA approval :( If not it'll be a texas mountain laurel.
