The Marathon Garden Club was organized in 1955 by a group of civic-minded residents who wanted to help improve the appearance of the area. In addition to its community involvement, the club encourages members to improve the gardens and landscaping of their own homes and neighborhoods. Classes are taught by local experts on topics such as floral arrangements, landscape design, conservation, and orchid growing. In addition to ongoing plant sales, the group hosts a Jamboree in January and a House and Garden Tour in March. The club is the only location in the Keys that hosts both a House and a Garden Tour.
