Plant Hardiness Zone Map

How to use the Plant Hardiness Zone Map

The U.S. Dept. of Agriculture established plant hardiness zones to help us plant the right plants in the right climates. The zone map was created to illustrate plant hardiness based on the weather year round.  This includes factors such as average low temperatures and special climate areas like the Great Lakes region. While not a hard and fast rule, planting outside of the recommended zone for a specific plant exposes you to a much higher chance of failure. For instance, a tree or shrub grown outside of its recommended zone may bud out too early for your area. If the early bud break is followed by a frost or too low of a temperature, this could damage the plant and even cause it to perish.

Please keep in mind that planting in the correct zone does not ensure survival. Other factors such as soil type, moisture, drainage, humidity, and exposure to sun and wind can have a direct effect on the survival of your plant.  Please review the descriptions for each tree or shrub on their individual product pages.

Each product page includes a plant hardiness zone map.  Please use it as a general guide on where the plant should grow.
