Helena Rutherfurd Ely (born Helena Rutherfurd: 28 September 1858 – 18 May 1920) was an American author, amateur gardener and founding member of the Garden Club of America whose three books influenced American and British gardeners to avoid Victorian formal gardens in favor of plantings that embodied an "informal and sensual style." She focused on planning her gardens around planting "hardy perennial plants found in the agricultural landscape."
Helena Rutherfurd was born on 28 September 1858. Helena was the one of five children from the marriage of Charlotte Livingston (1825-1894) and John Rutherfurd (1810-1871), a coal and railroad industry executive, and president of the Board of Proprietors for East New Jersey and the New Jersey Historical Society.
On 17 June 1880 at Trinity Church, in Newark, New Jersey, she married Alfred Ely II (1852-1914), son of Lucy Cooley and Alfred Brewster Ely, who was an attorney and partner in the New York City law firm Agar, Ely & Fulton. They had two children: a son Alfred (III) (1884-1959) and daughter Helena (1881-1970). While they resided in Manhattan, Helena and Alfred Ely owned a 350-acre country estate named Meadowburn Farm in Vernon Township, New Jersey. Part of Meadowburn was given to Helena by her mother as a wedding gift. The remainder, including the main house was purchased by Ely from the DeKay family, a colonial family that had settled in this area in the 1720s and played a prominent role in the New York–New Jersey Line War. The Rutherfurd family owned large tracts throughout Sussex County and was descended from early colonial proprietors.
At Meadowburn, Ely created formal and cottage gardens on five acres of the estate's grounds which served as the basis for a series of three books on gardening in which she favored perennials. Her first book, A Woman's Hardy Garden (1903) sold 40,000 copies and was reprinted 16 times before going out of print in 1930. She received fan mail and queries from fellow gardeners 20 years after her death.
