The Chautauqua Arboreum can be found in the 26-acre Colorado Chautauqua in Boulder, Colorado. Located on a National Historic Landmark, the arboretum celebrates the historic trees that have been on site since Chautauqua’s founding in 1898, while also acting as a community resource for plant species that can thrive along the Front Range. A mature urban canopy contributes to the camp-like feel in their community of public gardens, cottages, and community venues. Standouts include fourteen old-growth Colorado Blue Spruce trees towering over their central gardens, and many heirloom apple and pear trees that can be connected back to the orchard that once occupied the site. Today, the Chautauqua Arboretum identifies over 100 species of trees and woody plants on their campus of over 500 trees.

Additionally, many of their tree identification tags include Arapaho translations for the local plants. By adding the Arapaho names alongside the Latin and English plant names, the Chautauqua Arboretum fosters education and a lasting connection between people, plants, and place.
