Alicia Amherst was born in 1865 in Poole, Dorset, one of seven daughters of William Tyssen-Amherst, 1st Baron Amherst of Hackney, who was later the Conservative Member of Parliament for West Norfolk. Her mother, Margaret Susan Mitford, was an avid gardener and gave Amherst her own plot to care for at the age of ten. Her interest in history was spurred by access to her father's large library. In 1898, she married Evelyn Cecil and gained the second of the names under which she would publish, Mrs Evelyn Cecil. They had three children. Evelyn Cecil, a Conservative Member of Parliament, was knighted and, in 1934, raised to the peerage as Baron Rockley, so she became Lady Rockley of Lytchett Heath and then the dowager Baroness Rockley, two more names under which she would publish. She died in Poole in 1941.
Writing
Amherst became known for her first and still most famous book, The History of Gardening in England, published under the name Alicia M. T. Amherst. Unexpectedly for its author, it was a huge and immediate success. For the second edition, which was contracted within a month of the first, Amherst received ten times the amount she had been offered for the first. At the time, most gardening books were practical handbooks, and Amherst was the first writer to take a careful look at the history of gardening in England, going back much further in time than other gardening writers did. Indeed, she spearheaded the first wave of writing about Euro-American garden history, with such well-known works as Rose Standish Nichols' English Pleasure Gardens following in 1902 and Marie-Luise Gothein's A History of Garden Art in 1913. More scholarly but less eloquent than her contemporary Gertrude Jekyll, Amherst never became nearly as popular or influential a writer on gardening. But with its meticulous footnotes and exhaustive annotated bibliography, The History of Gardening in England became the authoritative work in its field and remains of value to historians today. Amherst wrote several more books, including two for children after she became a mother: Children's Gardens and Children and Gardens. Her London Parks and Gardens is the first serious and deeply informed book on London's open spaces. Amherst wrote a number of scholarly papers on garden history, as well as growing unusual plants in her own garden and collecting specimens on trips abroad for Kew Gardens.

Other botanical and horticultural activities
Amherst's collecting expeditions took her to Mozambique and South Africa, Rhodesia, and Ceylon, New Zealand, Australia, and Canada. This was a period when horticultural schools were being founded in England, and Amherst advocated on behalf of women entering the field. Amherst was also known as a fine artist of botanical and other subjects. In 1900, her husband published On the Eve of the War: A Narrative of Impressions During a Journey in Cape Colony, the Free State, the Transvaal, Natal, and Rhodesia and several of its illustrations were from sketches or photographs by Amherst. She took part in a campaign to save the Chelsea Physic Garden, a London garden dating back to 1673. She sat on its management committee, and the garden now holds her archive.
