This nationally recognized, historic estate garden is rich in plant diversity, habitats, and tranquility. Many bird and butterfly species are observed here. The garden acquired its present configuration in the two decades following John and Marie’s marriage in 1923. From the beginning, Wiles Creek served as a landscape focus and the forest shade determined the selection of plants. Tens of thousands of Virginia bluebells that now cover the hillsides in late April are the progeny of 500 plants they purchased.

In 1977, Marie Aull conveyed her cottage home, a 30-acre garden, and a maintenance endowment to Five Rivers MetroParks, with the provision that she be able to reside on the property as long as she lived while keeping her garden open to the public. Marie continued to direct the work of the gardeners after the donation of Aullwood Garden to MetroParks. Despite the help of gardeners, Marie could not resist working in the garden herself, even at age 90. Mrs. Aull was a familiar figure to those who visited her gardens.

The nature trail through the park is a combination of grass, gravel, soil, and pavement. It is flat, but not ideal for wheelchairs.
