Natural Dyes in Arizona

Hey All!! This sub has been incredibly helpful with tips and tricks for dying. I have a ton of Cochenial nearby that I've started collecting, processing, and dying with! But I would love to be able to make more colors from the plants in my backyard. I'm hoping and praying some of you might know where to find more options. I am in North Phoenix, but sometimes travel to Tuscon thank you!

tldr: Where can I find natural dyes in Phoenix?
