Tip Of The Day - 8/21/05 - Hardiness Zones
Found this and thought it would be a good "tip"
Probably the most important consideration in determining what garden and landscape plants you can grow is whether or not they will survive the climate in your area.
The USDA Plant Hardiness Zone Map factors in average winter minimum temperatures. This collection of information starts with Zone 1, where minimum temperatures can go down to MINUS 50 degrees Fahrenheit, and ranges to Zone 11, for the lucky gardeners in Hawaii and extreme Southern Florida where lows don't drop below 40 degrees Fahrenheit.
The data on which the USDA map is based was gathered over a period of 60 years.
