USDA Zone Map

Below is a listing of U.S. "Hardiness Zones" for seeds, bulbs and plants, as determined by the  U.S. Department of Agriculture. When ordering, you can determine if the item will be "Winter Hardy" in your area by checking the "Zone" information on the item's description page.

You may determine which climatic zone you are in by checking this map. However, this is only a guide since conditions for growing will vary in certain areas.

This map also serves as a rough guide for High Country Gardens’ Spring Bulb and Perennial shipping schedule. Each spring as products become available, we begin monitoring the weather and shipping orders once the threat of frost has been minimized. We start with the warmest zones (such as 8-10) and work our way north as spring arrives. In the fall, we reverse the process for fall bulbs as winter approaches.
