Rosedown Plantation is located in the West Feliciana Parish community of St. Francisville along one of the most historic corridors in South Louisiana. Daniel and Martha Turnbull began construction on the main house at Rosedown in 1834, completing it by May the following year. The home was furnished with the finest pieces available, most imported from the North and from Europe. The gardens were the province of Martha Turnbull throughout her life. The Turnbulls’ honeymoon in Europe included great formal gardens of France and Italy, an influence seen in Martha's activities at Rosedown. The gardens grew out from the house over a span of many decades, to cover approximately 28 acres. In the 19th century, Rosedown was one of the few privately maintained formal gardens in the United States. A restoration of the formal gardens in the late 1950s was done by Catherine Fondren Underwood and Ralph Ellis Gunn, using Martha Turnbull’s extensive garden diaries. When possible, the same species and varieties were replanted. When plants in Martha’s inventory were discovered to be no longer available, the staff of gardeners would propagate them from plant stock surviving in the gardens. Through this process, the gardens, as well as the house, were returned to their original state.
