Your planting zone — the USDA plant hardiness zone — tells you which perennial plants survive your winters, based on the average annual minimum temperature for your area. Enter your ZIP code to see your growing zone, its temperature range, and your frost dates, then use them for choosing plants and timing sowing and transplanting. ZIP codes are grouped by state below, and every figure is drawn from the 2023 USDA plant hardiness zone map.
