Nannine Clay Wallis Arboretum in Paris, Kentucky, is a four-acre public nonprofit arboretum built around a house from 1851, with its earliest trees planted in the mid-1850s. Its development was shaped largely in the first half of the 20th century by Nannine Clay Wallis, a founder and later president of the Garden Club of Kentucky and a leader in wider garden-club organizations. Known as one of central Kentucky’s finest old-tree collections, it holds about 70 tree varieties, including notable large specimens, and also includes gardens, a reflecting pool, and a pavilion. It endures as both a public green space and a link between 19th-century planting and 20th-century civic horticulture.
