Being an amateur gardener, I can only touch on the idea of plants native to an area versus those which have been imported. I would assume ones which can somehow be confirmed as native have adapted to the Fool's Spring conditions in which they not only survive, but thrive.
Had I been asked, as I am familiar with that part of America, I would have guessed either Utah or Arizona. Thank you for the confirmation. Sedona is very well known for that type of scenery. I hope you realize your vision of living there one day!
