Ellen Ann Willmott (19 August 1858 – 27 September 1934) was an English horticulturist. She was an influential member of the Royal Horticultural Society, and a recipient of the first Victoria Medal of Honour in 1897. She cultivated more than 100,000 species of plants, and sponsored expeditions to discover new species. More than 60 plants have been named after her or her home, Warley Place.
Ellen Willmott was born in Heston, Middlesex, the eldest of three daughters of Frederick Willmott (1825–1892), a solicitor, and Ellen Willmott (d. 1898). She and her sisters attended the exclusive Catholic convent school Gumley House for several years. In 1875 the family moved to Warley Place at Great Warley, Essex, which had 33 acres (130,000 m2) of grounds; this was to be Ellen’s lifelong home. The family were keen gardeners and developed Warley Place’s gardens together. One of the most ambitious developments was an alpine garden, including a gorge and rockery (pictured), which Ellen's father gave her permission to create on her 21st birthday.
Willmott inherited Warley Place on her father’s death and continued to develop the gardens, indulging her passion for collecting and cultivating plants. She is thought to have cultivated more than 100,000 different species of plant.
Willmott employed up to 104 gardeners, and was known for being a demanding employer; she would reputedly sack any gardener who allowed a weed to grow among her flowers. She only employed men in her garden; she was once quoted as saying "women would be a disaster in the border".
She was also known for being a prodigious spender. In 1905 she bought a third estate in Ventimiglia, Italy. Willmott used her wealth to fund plant-hunting expeditions to China and the Middle East, and species discovered on these excursions would often be named after her. The expeditions she sponsored included those of Ernest Henry Wilson, who named Ceratostigma willmottianum, Rosa willmottiae and Corylopsis willmottiae after her.
Willmott joined the Royal Horticultural Society in 1894 and became a prominent member, elected to the narcissus, floral (group B) and lily committees. She helped to persuade Sir Thomas Hanbury, her neighbour at Ventimiglia, to purchase the site at Wisley which became the RHS Gardens and donate it to the society, and was appointed a trustee of the RHS Gardens in 1903.
Willmott was one of only two women, alongside Gertrude Jekyll, to receive the Victoria Medal of Honour in 1897 (newly instituted that year for Queen Victoria’s Diamond Jubilee). In 1905 she became one of the first women to be elected a fellow of the Linnean Society of London. She also received the grande médaille Geoffroi St Hilaire from the Société d’acclimatation de France in 1912, and the Dean Hole medal from the National Rose Society in 1914. She published two books; Warley Garden in Spring and Summer in 1909 and The Genus Rosa, published in two volumes between 1910 and 1914. It includes 132 watercolours of roses painted by Alfred Parsons between 1890 and 1908, which are now held by the Lindley Library in London (Cory Bequest). Willmott also commissioned Parsons to paint her three gardens. Queen Mary, Queen Alexandra, and Princess Victoria are known to have visited her at Warley Place. In 1914 she initiated a bitter public spat with the horticulturalist E.A. Bowles about some observations on rock gardens made by Reginald Farrer in his foreword to one of Bowles' books.
Willmott’s prodigious spending during her lifetime caused financial difficulties in later life, forcing her to sell her French and Italian properties, and eventually her personal possessions. She became increasingly eccentric and paranoid; she booby-trapped her estate to deter thieves and carried a revolver in her handbag. She was arrested on suspicion of shoplifting in 1928, although later acquitted.
Willmott died of atheroma and embolus of the coronary artery in 1934, aged 76. Warley Place was sold to pay her debts and the house was demolished in 1939, although plans to develop a housing estate on the site were rejected. It was later designated as green belt and became a nature reserve.
