search yahoo…zones for planting, and click on the first one that comes up.
Here is the gardening zones for the US
The lower the number the higher north it is the higher the more down south, you can plant any kind of annuals you want in any zone because they dont come back. If you buy a perrenial make sure it for your zone. Some plants need cold to go dormant other will die in the cold. It’s really quite simple once you know your zone, good luck
The USDA publishes one, should be able to check it out at www,usda.gov (Ithink that is right). Anyway, Chicago is a zone 5-6, New York is a 7, SanAntonio an 8, Las Vegas a 9. I have a map, email me if you have a problem.
