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.

Gardening Tip of the Day

  • Both Italian and curly parsley are excellent sources of vitamin A and C. Richer in iron than any other green vegetable, parsley is appreciated by cooks for its ability to blend various flavors in soups, stews, sauces and salads. Either variety can be used fresh, dried or frozen. Flat-leafed Italian parsley has a better flavor for cooking, while curly parsley is commonly used dried in cooking and fresh as a garnish. Start from seed indoors or set out plants when all danger of frost has passed.
