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

  • How well soil drains is critical to gardening success. Here is an easy to follow method to evaluate your garden.

    1. Remove both ends of a large 48-ounce juice can.
    2. Dig a 4-inch-deep hole in the garden.
    3. Set the can in the hole and backfill around it with soil.
    4. Fill the can with water<BR>
    5. Check to see how much of the water has been absorbed after 1 hour.

    If the level drops about 2 inches, you’re in good shape. If the level drops more than 4 or 5 inches, you need to add organic matter (compost). If the level drops less than 1 inch, dig a pond or build raised beds. The soil has very poor drainage.
