Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Alpine you can estimate when it's a good idea to plant creeping zinnia by referring to the USDA zone info.
