USDA Hardiness Zone Map
USE MAP ONLY AS A GUIDE
Many variables determine a plants true adaptability including rainfall, humidity, soil, elevation, light, age and cultural maintenance. ZONE MAP does not determine plants adaptability to given locality but indicates minimum expected temperatures for region and how it relates to a plant's chances of survival at that temperature.
Throughout our site, we have listed Zones of Hardiness for each plant we offer. However, on a small map such as this, it is difficult to show all of the local variations and climactic changes within each zone. Most nurserymen agree that zone designations for plants are approximate.
Many plants can be grown in one zone "colder" than rated by simply placing in a protected location or by proper winter care (such as mulching). A southern exposure protected from winds will often allow one to plant specimens normally expected to grow only in warmer climates. Many houses have areas protected by two sides of an "L" and that protected spot will act ten degrees warmer than the open yard, even in the coldest weather.
Do not be discouraged from attempting to grow a "Zone 5" plant in "Zone 4", or a "Zone 3" plant in "Zone 2". Just try to think of a spot in your landscape that is a little more protected.
