Zone Lookup

This new simplified plant zone map issued in 2012 is available to view in full detail on the USDA website. There is an interactive feature that allows you to find your hardiness zone by typing in your zip code. (Please note: The USDA zip code lookup will display either an 'A' or 'B' along with your zone number. We do not use the 'A' or 'B' when recommending zones on our products, just the base number.)

Click on the map below to go to the USDA web site to look up your hardiness zone!

Hardiness zones are based on the average minimum temperatures for each zone. Lower numbers indicate the most northerly area where plants will survive the winter and higher numbers are the most southern area where they will perform consistently. Recommended plant zones are meant for guidelines only. Other plant growth factors may affect hardiness such as rainfall, wind, humidity, soil type, altitude, sunlight and cultural practices. Local climates may vary considerably. It's always best to use your instincts, observe other gardens in the area, and be willing to do some experimenting with plant locations and plant protections.
