The Bartlett Arboretum is a 20-acre arboretum in Belle Plaine, Kansas. It was named after its founder, Dr. Walter Bartlett, who started the place in 1910. It was used in the 1930s as a test site for the US Department of Agriculture. The government agency used it to test trees from all over the globe for hardiness.

History says that the land was once a barren area. Thanks to Dr. Bartlett, it was developed to what it is today. He built a dam and four islands in the slough, he also landscaped the site. Today, visitors can find massive oaks, cypress, and Japanese maple trees on the site.

Although, privately owned, the Bartlett Arboretum is open to the public upon special request. Those interested can contact it through their official website.
