This 80 acre site is in the northeast corner of the campus of Hillsdale College. It was started by a donation of 14.5 acres by Mr. and Mrs. George Slayton in 1922. Professor Betram Barber began developing the property with ornamental plants in the 1920s. Today the gardens are notable for stately mature trees, semi-natural settings, and collections of conifers, magnolia, viburnum, witchhazel, mountain ash, maple, oak, and hickory as well as several genera of hardy deciduous shrubs.
