She was born Frances Everett in
Enfield,
Middlesex, where she lived most of her life at
Bulls Cross. She was educated at
Enfield County School and
Swanley Horticultural College (now
Wye College, part of the
University of London). Her mother took her as a child to the
Chelsea Flower Show. Her next-door neighbour,
E. A. Bowles, Vice-Chairman of the Council of the
Royal Horticultural Society (RHS), guided her interest in plants and in 1927 recommended her to Amos Perry, a local plant nurseryman. She worked in Perry's Hardy Plant Farm, soon managing his water-plant department and helping with exhibits at the Chelsea Flower Show. She married Perry's son Gerald, (d.1964) an expert on ferns and water plants. Through her work with Amos Perry she became knowledgeable about hardy
perennials and is known particularly for her writings about them. From 1943 to 1953, she was horticultural adviser to
Middlesex County Council and later principal organiser for agricultural and horticultural education in
Middlesex. In 1953 she was appointed Principal of Norwood Hall College for adult education, a post she occupied until 1967. In 1960, she sat on the
Royal Commission on
allotments. In 1968 she became the first woman council member of the RHS. The absence of women on the council had been fiercely debated in the letters column of
The Times and in an editorial article. When Frances Perry was nominated she responded, "If you want me because I am a woman, the answer is no, but if you want me because of anything I have done in horticulture, the answer is yes." She became a vice-president of the Society in 1978. In the 1960s, she became a champion of
Capel Manor horticultural college near her home in Enfield and she continued to support it until her death She contributed a gardening column to
The Observer newspaper for over twenty years. She was a contributor to the
BBC radio programme
Home Grown, presented by
Roy Hay and
Fred Streeter in the two o'clock slot on Sunday afternoon later to be occupied by ''
Gardener's Question Time'', and she was one of the first TV gardening personalities. On retirement from Norwood Hall she remained active in horticultural research. She visited over seventy countries, often in the company of
Roy Hay (1910–1989), a long-standing gardening colleague, whom she married in 1977. One of her last major journeys was made at the age of 84, when she toured botanical gardens in Germany. After the death of Roy Hay, Frances Perry left Enfield to live with her son in
Devon. ==Honours and awards==
