New at the Morris Arboretum this summer is an exhibit called “Tree Adventure.” Opening July 4, it explores the relationship between plants and people through a central theme: We need trees, and trees need us.

Armed with a Passport to Adventure, visitors can explore the Arboretum’s vast 92-acre garden to learn about the critical role trees play in our environment, while having fun engaging with the natural world. The five-part exhibit is an accessible and fascinating learning experience for both children and adults.

The exhibit’s main attraction is “Out on a Limb,” a 450-foot long walkway 50 feet above the ground that allows visitors to get a bird’s eye-view of the forest.

People can learn about plant explorers and the history of “living fossils” at the Dawn Redwood Grove, and how tree roots work and grow at Oak Allée.

At the Springhouse, patrons can travel back to pre-Victorian and Colonial times when the springhouse was the best means of refrigeration. The Log Cabin enables visitors to experience life in another era when people depended on trees to build homes, keep warm, find and store food and raise their family.
