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

What Are Planting or Growing Zones?

In the United States, planting zones are specific locations that correspond to which plants can grow well there. The planting zone map is based on the average annual minimum winter temperature, and which varieties of flowers and plants can survive and thrive in those conditions. There are a total of 11 growing zones in the United States as defined by the USDA, of which 8 are located in the lower 48 states.

How Do I Find Out Which Planting Zone I'm In?

The best way to find out which growing or planting zone your garden is in is to use our convenient zone finder tool found at the top of this page. Simply enter your zip code and get information on your planting zone. Remember that zone maps cannot account for deviations in typical zones such as micro-climates or if your location is associated with unusual conditions for the region. Always remember that zone maps are not perfect and that elements like soil, moisture, humidity, heat, or other weather conditions at the time can influence how well your plants will grow in any particular US planting zone.

How Can I Tell Which Growing Zone a Plant Will Thrive In?

You'll find USDA hardiness zone designations at the end of many plant descriptions on the Breck's website and in our free print catalog. A variety marked "Zones 3-8," for example, should grow and thrive in planting zones 3, 4, 5, 6, 7, and 8.
