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.
