Hortulus Farm is an 18th century farmstead, public garden and horticulture education center situated among the bucolic rolling hills of historic Bucks County, Pennsylvania. An original 1683 William Penn land grant, the farm functioned as a major dairy operation by the Warner-Thompson families until the Great Depression. Since 1918, the farm changed hands many times until 1980 when famed garden and event designer Renny Reynolds and noted garden author Jack Staub purchased the farm. They restored the property with 24 exquisitely designed floral and vegetable gardens and built a horticulture education museum in one of the barns. The museum includes paintings by local Bucks county artists, antiques, horticulture books, and letters from renowned gardening experts. The classic Isaiah Warner stone house on the property was built between 1793 and 1830. It was added to the U.S. Registry of Historic Places in 2004. Reynolds and Staub currently reside in the house with their unique collection of hand-crafted furniture, artwork, antiques, and majolica. In addition to the 24 distinct formal gardens, Hortulus boasts a rotating outdoor sculpture collection, a picturesque statue pool, horses, sheep, peacocks, and diverse pond waterfowl, and a nursery with unique topiaries and other notable plants, A longtime member of Greater Philadelphia Gardens, in 2015 Hortulus Farm was honored by being made the second-only-in-their-history Affiliate Garden of The Garden Conservancy, giving it major new national prominence. It is also the second ever Affiliate Garden of The Garden Conservancy's preservation program, giving it major national prominence.
