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

Gardening Tip of the Day

  • Tailor the menu at your bird feeders to discourage unwanted visitors. Thistle seed attracts finches, pine siskins and redpolls, but most sparrows, squirrels and blackbirds do not care for it.
    Safflower seed attracts cardinals and discourages squirrels and sparrows. To discourage pigeons avoid ground feeding and use seed mixes without cracked corn.
    Before filling feeders for the first time this fall, thoroughly clean them using a 10% bleach to water solution. Do the same for birdbaths and houses.
