Colorado Interactive Plant Zone Hardiness Map

Plant Maps has added a new interactive Colorado Plant and Tree Hardiness Zone Map based on the 1990 USDA Hardiness Zone Map.   Colorado covers a wide range of growing zones and this new interactive map allows the user to zoom to the city and street level to determine the exact gardening zone.  Hardiness zone (sometimes referred to as Growing Zones or Gardening Zones) are used by gardeners to determine the ability of a plant or tree to survive a minimum temperature in that zone.

Plant Maps also allows users to locate their gardening  zone by entering a zipcode in the planting zone to zipcode search tool.
