Tolerance Of Indian Hawthorne, Too Low Temperatures

Question

We live in northern Scottsdale at an elevation of about 2000 feet. We would like to plant the Indian Hawthorne on the wall in the attached photograph, but worry about low temperatures in the winter. Temperatures may drop to 25 to 27°F for a few days, with an occasional freeze. The location receives full sun and will be on a drip system. Do we have anything to worry about? Thank you for your help.

Answer 1

Indian Hawthorne is rated for hardiness zones 8-11. Scottsdale is in USDA Hardiness zone 9, so it should be fine.
