Find Your Planting Zone

The USDA Plant Hardiness Zones offer 10 basic classifications (Zones 1 to Zone 10) to help growers decide what varieties are best suited for their environment. The zones are based on average annual minimum temperatures.

Colorado is in Zones 4 to 7. The Colorado mountains average minimum temperatures in Zone 4 are -30 to -20 F. The Colorado plains and western slope are between Zone 5 to 7 which averages -20 to 10 F. 

InColor annual flowers will not survive Colorado winters, however InColor perennials, shrubs, and trees will be marked with a zone range for you to check to ensure they will come back year after year!
