This calculator uses data from the National Centers for Environmental Information (NCEI) and the National Oceanic and Atmospheric Administration (NOAA) to help determine your USDA Hardiness Zone and estimate typical first and last frost date ranges. Results are based on approximately the last 30 years of historical data and do not account for site-specific variables such as garden microclimates, elevation, local wind patterns, or current and future weather conditions. Always monitor your immediate local climate, especially when planting near the limits of a plant’s hardiness range. As outlined in our terms and conditions, customers are ultimately responsible for selecting appropriate delivery timing for plants.
