Growing Zone Information

  zone map key code


This USDA map divides the country into PLANT HARDINESS ZONES based on average lowest winter temperatures (see map below). We include ZONE ranges in our descriptions of hardy plants so you can tell if the plants you choose can survive in your location or the location of a gift recipient. We ship live plants, roots and bulbs at the right time for planting for your zone.

For annuals we list your expected Spring frost free date - this is helpful in determining when you can safely plant annual seeds and plants.

Your Zone Zone 10 Zone 9 Zone 8 Zone 7 Zone 6 Zone 5 Zone 4 Zone 3
Your Lowest Temp (F.) 30° to 40° + 20° to 30° 10° to 20° 0° to 10° -10° to 0° -20° to -10° -30° to -20° -40° to -30°

Gardening Tip of the Day

  • Washing large amounts of fall- and winter-harvested root crops like turnips, parsnips, rutabagas, leeks and carrots can be a messy chore, particularly if you try to do it in the kitchen sink. To quickly wash vegetables, place them in a plastic clothes basket and hose them down. The muddy water flows through the holes in the basket and you're left with clean produce.
