Plant Hardiness Zones
The Plant Hardiness Zones divide the United States and Canada into 11 areas based on a 10 degree Fahrenheit difference in the average annual minimum temperature. The United States falls within Zones 2 through 10.
Suggested hardiness zones have been indicated for all trees and perennials available. If zones 4-9 is indicated, the tree or perennial is known to be hardy in zones 4, 5, 6, 7, 8, and 9. Suitable hardiness means a plant can be expected to grow in the zone's temperature extremes, as determined by the lowest average annual temperature.
