map helps you avoid mistakes. All plants in this cata- 
log carry a zone number. By matching this number to 
the number indicated on the map for your location, 
you can order with safety. Plants with smaller zone 
numbers should also be hardy in your area. Fre- 
quently, too, a plant rated one zone higher will grow 
well in a protected area.
