Aldridge Gardens is a 30-acre public garden located in Hoover, Jefferson County. Best known for its multitude of hydrangea varieties, the facility was founded by property owners Eddie and Kay Aldridge with the intent of preserving the natural beauty of their estate for the public.
In 1966, Eddie Aldridge first became aware of the property that now makes up Aldridge Gardens when he and his father were hired to plant three magnolia trees on what was then the estate of John Coxe. When the estate came up for sale in 1977, Aldridge bought the property, which he long had thought should be developed and preserved as a community resource.

Aldridge Gardens is probably best known for the numerous native oak-leaf hydrangea shrubs on the grounds. These plants include a unique variety known as "Snowflake," discovered by Aldridge and his father in 1969. The two men patented the variety in 1971 and began shipping it to nurseries and garden centers around the world. Through their efforts, the plant, which was once rare, is now found in gardens on almost every continent.
Since the initial development phase of the gardens, a 2,500-square-foot pavilion and a new entrance plaza and camellia garden have been added. Aldridge Gardens is a popular wedding venue and attracts more than 80,000 visitors each year, who attend seminars, concerts, and a variety of events including Paws-in-the-Gardens (a dog festival), Hooks-in-the-Gardens (a week-long fishing event for children in spring), an annual art show, a garden gala fundraiser, plant sales, and a Native American festival.

Aldridge Gardens is owned by the city of Hoover, and its operations are overseen by a board of directors; a staff of eight runs the day-to-day operations of the public garden. The facility is open daily, except Christmas and New Year's Days. The Kay and Eddie Aldridge Art and Historical Collections Museum is open daily except during private events.
