Colorado, known for its breathtaking landscapes and diverse climate, is located in the western United States. The state experiences a wide range of climates, from the arid regions in the south to the alpine tundra in the Rocky Mountains. As a result, determining the appropriate garden zone for Colorado can be a complex task.
The garden zone system, developed by the United States Department of Agriculture (USDA), is used to identify the most suitable plants for specific regions based on their hardiness to cold temperatures. Garden zones are determined by average annual minimum temperatures, with lower numbers indicating colder climates. In Colorado, the garden zone can vary significantly depending on the location and elevation.
1. What garden zone is Colorado in?
