Nancy Olson Children's Garden

NOTE: This garden is currently closed for construction. Stay tuned for updates!

The Nancy Olson Children’s Garden is located inside the East Loop of the Arboretum. You’ll know you’re there when you come to the koi pond with its charming wooden bridge. Named in honor of a devoted Klehm member, the garden is designed to encourage children to explore the many wonders of nature. Children love navigating the hedge maze to find the surprise waiting for them at journey’s end. The Rainbow and Alphabet Gardens are colorful and educational delights. Don’t forget to say hello to Cow-li-Flower, the Garden’s bovine mascot, before leaving. An octagonal pavilion offers a place for picnicking and can be rented for parties and special events. A children’s water feature with splash pad and babbling brook will be constructed for 2018.  This will be a fun, safe play area for all the little ones to cool off on a hot, summer day!
