Zone 7b in Prescott

On the 2023 USDA Plant Hardiness Zone Map, Prescott falls in zone 7b. That means the coldest night of a typical winter drops to between 5 and 10 °F. Perennials, shrubs and trees labeled for zone 7b or colder (a lower number) should survive the winter here.

A zone only covers winter cold. For a plant to do well it also needs the right amount of sun, and that varies far more from one corner of a yard to the next than the zone does across town.

What “full sun” means in Prescott

Full sun is 6+ hours of direct sun. In Prescott an open spot has 14.5 hours of daylight to work with in June and 9.8 in December, so a bed that clears 6 hours in summer can easily drop to part shade in winter once the low sun slips behind trees and houses.
