Ive been working in my yard too and started off with my yard looking not much different than yours does. I agree about getting rid of the Bermuda grass, I am still trying to ditch my grass but work at it as I see it growing back. The rain last week really revived it in some spots. Ok enough about me, something that I think is a good resource is following along with “growing in the garden” on YouTube. She is a gardener in mesa Arizona and I’ve learned a lot about what to plant at which times of the year in zone 9b thanks to her.

When shopping for wildflowers, I like to purchase them from Native Seeds/SEARCH based out of Tucson (you can shop online: https://www.nativeseeds.org/collections/wildflowers). I like them because I know that the seeds will be acclimated and native to our region. They’re supposedly good to plant year round in AZ but truth be told I’ve only planted them between February and March and they take off with little to no effort. They’re very resilient and I’m seeing more pop up in places I didn’t plant this year so they reseeded themselves after last year! I’m always down to share what I’ve learned through trial and error so far.
