Planting Fields Arboretum State Historic Park, Arboretum and historic house in Oyster Bay, New York, US.
Planting Fields Arboretum State Historic Park is a historic estate with tree gardens, greenhouses, and a Tudor Revival mansion in Oyster Bay, New York. The grounds cover roughly 400 acres (162 hectares) with formal garden areas, lawns, wooded trails, and plant collections from different climate zones.
William Robertson Coe bought the property in 1913 and hired landscape architects from Boston to shape the gardens and grounds. The mansion was completed in the 1920s, and the estate later became public property under state management.
The estate takes its name from the original planting projects that transformed farmland into a designed landscape. Today visitors come to walk the trails, explore seasonal blooms in the gardens, and view the interiors preserved from the early 20th century.
The greenhouses open Wednesday through Monday between 10am and 4pm, while guided mansion tours run Thursday through Sunday. Garden paths are mostly level and accessible for wheelchairs, though some wooded trails are more uneven.
The main greenhouse holds the largest camellia collection in the northeastern United States, with hundreds of varieties blooming through winter months. Alongside the camellias, tropical hibiscus, orchids, and rotating seasonal displays grow under glass year-round.
