United States Department of Agriculture - Hardiness Zone Map

Plant hardiness is very important to growing success. Check the map to determine which hardiness zone you live in, or enter your zip code in the box below to find your zone. You'll find zone designations at the end of many of the plant descriptions on this site and in the print catalog. A variety marked "Zones 3-8," for example, should grow and thrive in zones 3, 4, 5, 6, 7 and 8.
