Local nurseryman Eddie Aldridge purchased the property from the Coxe family in 1977 as a residence. Aldridge, who along with his father, Loren L. Aldridge, found and patented Hydrangea quercifolia 'Snowflake', a double-flowering form of Oakleaf Hydrangea. In 1997 the gardens were conveyed to the City of Hoover and formally dedicated to the public. The site is now managed by a non-profit organization. A new master plan was approved in 1997 to guide the future development of the gardens.
The gardens contain extensive hydrangea plantings, as well as a five acre (20,234 m²) lake with walking trails. Public lectures and educational activities are scheduled throughout the year.
