The Peony Garden, established in 1922, features over 800 individual plants and hundreds of varieties of historic peonies.
The arboretum's terrain was significantly shaped by glacial activity, resulting in the distinct steep valleys and moraine topography found throughout the site.
It is home to the James D. Reader Jr. Urban Environmental Education Center, which supports academic research and community programs.
The site hosts a collection of rare and endangered native Michigan plants, including species of ferns and orchids.
The Huron River flows directly through the property, providing a riparian habitat that supports local waterfowl and wildlife.
Portions of the landscape utilize controlled burns to maintain and restore native tallgrass prairie ecosystems.
The University of Michigan Nichols Arboretum, known as the 'Arb', is a 123-acre landscape featuring a mix of native woodlands, prairie restorations, and specialized plant collections. It is distinguished by the Peony Garden, which contains North America's largest collection of historic herbaceous peonies. The grounds follow the Huron River, incorporating a variety of terrains ranging from steep, wooded ravines to open meadows. It serves as an outdoor laboratory for the University of Michigan, housing diverse botanical displays including the Dow Field and the Gateway Garden. Visitors can explore a network of over three miles of trails that connect the arboretum to the main university campus and surrounding parklands. The site functions as both a recreational space and a research facility dedicated to environmental education and conservation.
