Colorado Native Range
Colorado provides several different habitats for its native flowering plants and wildflowers. These habitats stretch across various ecosystems, from the Rocky Mountains to the wildflower-rich Great Plains.
Some of Colorado’s ecosystems contain a high ratio of endemic flowering plants and wildflowers. An endemic species is one that grows in a very particular area or ecosystem. It’s estimated that on the Colorado Plateau, over 10% of the plant species are endemic to this area.
Colorado is situated in the Midwestern region of the United States and has five USDA Hardiness Zones. Colorado’s native flowering plants and wildflowers are perfectly adapted to survive in USDA Zones 3 to 7a. Most of Colorado falls under Zones 3 to 5, with a few western and southeastern areas being in Zones 6 and 7a.
How Are Native Colorado Flowers Defined?
With many gardeners across Colorado bringing exotic or imported plants, some of these species can become naturalized across the state. So how are Colorado’s native plants defined and separated from non-native species?
Plants are defined as native to Colorado if they grew in the region before European settlers arrived in the 1850s. As such, many of Colorado’s native plants were used for food, medicine, or other purposes by Native American societies.
When Are Native Colorado Flowers in Season?
Colorado’s highly variable climate can be a challenge for native flowering plants. Most of Colorado’s native flowering plants bloom from summer until fall, depending on the weather. Warmer temperatures and reduced risk of frost particularly benefit Colorado’s native wildflowers, which prefer to bloom during the summer.
Some of Colorado’s native flowering plants, such as blue flax and prairie smoke, bloom during the spring. These early blooms provide vital nectar for pollinators such as solitary bees.
50 Native Colorado Flowers, Flowering Plants, and Wildflowers:
