Denver Botanic Gardens

Founded in 1951, the mission of Denver Botanic Gardens is to connect people with plants, especially plants from the Rocky Mountain region and similar regions around the world, providing delight and enlightenment to everyone Located in the middle of the Mile High City, Denver Botanic Gardens was one of the first gardens in the country to emphasize native plants and to champion environmentally responsible practices, such as water conservation and biological control of pests. Today, Denver Botanic Gardens continues this tradition at three unique sites: Denver Botanic Gardens, Denver Botanic Gardens at Chatfield and Mount Goliath. Each of these demonstrates the varied ecosystems of Colorado.
