About
Nichols Arboretum is a natural oasis blending botanical splendor with tranquil landscapes.
This 128-acre haven, affectionately known as "The Arb," is managed by the University of Michigan and offers a captivating escape with its diverse plant collections, rolling woodlands, and scenic trails along the Huron River. It stands out as a living laboratory and a beloved public green space, showcasing both curated botanical displays and wild, natural beauty.
Visitors can wander through picturesque landscapes featuring over 400 plant species, including a significant collection of 110 tree types. A signature highlight is the W.E. Upjohn Peony Garden, home to the largest collection of heirloom peonies in North America, boasting nearly 800 plants and over 10,000 blooms during peak season. Beyond the peonies, explore areas like Heathdale with its Appalachian plants, the expansive Dow Prairie, and the serene Huron River frontage.
Whether you seek a peaceful stroll, a vibrant photographic subject, or a moment of reflection amidst nature, Nichols Arboretum provides a memorable experience. Its blend of botanical research, historical collections, and stunning natural features makes it a truly unique destination that continuously delights and educates. Don't forget to bring the Snappit nature identification app along to scan local species.
The origins of Nichols Arboretum trace back to the early 1900s, when University of Michigan botany professors sought a larger site for a botanical garden. Renowned American landscape gardener and University of Michigan alumnus O. C. Simonds designed the arboretum, which officially opened in 1907. The 128-acre site was partially donated by Esther Connor Nichols and her husband Walter, from whom the arboretum ultimately derives its name. Initially intended as a botanical garden, the hilly terrain proved unsuitable for extensive greenhouse research, leading the botany faculty to establish a new garden elsewhere by 1914. Responsibility for the site was then transferred to the landscape architecture faculty, and it was officially named Nichols Arboretum in 1922. A significant addition came in 1922 when William E. Upjohn, a University of Michigan Medical School alumnus, donated his personal collection of peonies, forming the basis of the now-famous Peony Garden, which opened to the public in 1927. Many of the arboretum's older plantings date from the 1920s and 1930s.
