Alys Fowler (born 9 November 1977) is a British horticulturist and journalist. She was a presenter on the long-running BBC television programme Gardeners' World.
Fowler was born in Silchester, Hampshire, and had a rural childhood. Her father was a doctor, and her mother ran various businesses – she had 200 chickens and sold their eggs, trained gun dogs, and would dog-sit for Londoners. She was influenced by her mother's gardening talents and the degree of self-sufficiency it afforded the family. After leaving Bedales School in 1996, she studied at the Royal Horticultural Society, and the Royal Botanic Gardens, Kew in London, where she became interested in bringing a more organic and accessible aesthetic to landscape gardening. In 1998, she was awarded a Smithsonian Scholarship to study at the New York Botanical Gardens based in the Bronx.
Fowler returned to the UK in 1999 to attend University College London, where, in 2002, she completed a master's degree in Society, Science and the Environment.
Fowler began working as a journalist for Horticulture Week, and Landscape Review.
In 2005, she worked for BBC Gardeners' World and Parks as a horticultural researcher. In 2006, she became Head Gardener of the BBC garden at Berryfields in Stratford-Upon-Avon, and created features at the Gardeners' World Live shows.
In 2007 she published The Thrifty Gardener: How to Create a Stylish Garden for Next to Nothing.
In 2008, after appearing occasionally in her Berryfields role, she became a regular presenter on Gardeners' World, and wrote a monthly blog on the programme's website. She was dropped by the BBC for the 2011 series, at the same time that Toby Buckland's contract as main presenter was not renewed.
