Climate zones in North America
This map can be used to help you select the best plants for your garden, and to determine when to plant. It is simple to use, all you have to do is locate the zone where you live, and then choose plants with your zone listing.
Some of the flowers and plants on our website have the zone ranges indicated. Most plants can grow successfully in a range of zones. Some plants, such as perennials, biennials, and bulbs, are more zone specific and should only be grown in the recommended zones. But annuals grow in almost any zone, providing they are given the correct amounts of water and sunlight, and the soil contains the proper nutrients.
The zones on this map represent the average minimum temperatures in each area. The zones actually blend into each other, and within each zone there are microclimates that can be colder or milder than the surrounding area. Use the map only as a guide to selecting plants for your garden. When buying plants at your local garden center you may want to ask questions concerning specific plants in your geographical climate.
