Bartlett Arboretum, Arboretum and Historic Place in Belle Plaine, United States.

The Bartlett Arboretum is a tree garden in Belle Plaine with carefully maintained collections of woody plants across its grounds. The layout includes different conifer species, oaks, and ornamental trees planted in organized patterns throughout the property.

Dr. Walter Bartlett founded this place in 1910 by transforming open pasture into a structured plant garden. It evolved from a private endeavor into a site of local historical importance, now protected as a registered landmark.

The arboretum's name honors Dr. Walter Bartlett, who bought the land in 1910. From 1926 to 1942 it hosted annual tulip shows, and in the 1930s the USDA sent plants here for hardiness trials. Today outdoor concerts are held on a stage with seating, and the site is run by steward Robin Lynn Macy, a founding member of the Dixie Chicks.

The arboretum is privately owned and not freely open: visits are by appointment only, so arrange access in advance. It lies at the junction of Kansas Highway K-55 and Line Street in Belle Plaine, about 20 miles south of Wichita. The grounds cover roughly 6.2 hectares (15 acres) and include a stage and seating area for outdoor concerts.

At the property edge sits a converted train station from the old Santa Fe Railroad era, now used as an art studio. This unusual combination joins transportation history with creative work happening on site today.
