Aullwood Park, located in Dayton, Ohio, is a 31-acre park that was donated by Marie Aull to the Five River Metroparks in 1977. It's an historic estate garden with numerous native and exotic flowers.
There are hiking trails through the park that allow you to enjoy all of the beautiful plants. Every season is different. In the spring, you'll see tulips, daffodils, lenten roses, and wildflowers. In May, the Lilac Lawn smells absolutely heavenly. You might even see clematis vines growing in the shrubs. In June, look for the gorgeous peonies. And in July and August, check out the butterfly garden, magic lilies, and begonias.
If you visit the park, take the time to find these attractions: a bur oak tree with the 1913 flood watermark, and a twin sycamore tree that was alive in 1492, when Columbus discovered America.
The gardens are open April 1 - October 31 from 8 am - 10 pm, and November 1 - March 31, from 8 am - 8 pm. Since it's part of a park, admission is free.
