Your plant hardiness zone helps determine which plants, including roses, will thrive in your climate. The best way to find your zone is by using the USDA Hardiness Zone Map (for the U.S.) or the Canada Plant Hardiness Zones Map (for Canadian gardeners).
These maps are widely used by gardeners, nurseries, and plant experts, though they don’t account for factors like snow cover, freeze-thaw cycles, soil drainage, or microclimates within the same zone. Still, they remain the most reliable guide.
