Matt Keightley is an award-winning garden designer with more than 12 years' experience in the landscaping industry and a reputation as one of the UK's most exciting young garden designers.

He made waves within the landscaping industry in 2014 when, as a debutant at the RHS Chelsea Flower Show, he was awarded the RHS Silver-Gilt Medal and the highly acclaimed BBC People's Choice Award for his 'Help for Heroes' show garden, dedicated to the wounded men and women of the armed forces. One year later he was back at Chelsea, this time working with Prince Harry for his charity Sentebale.

Matt's 'Hope in Vulnerability' show garden earned him another Silver-Gilt Medal and the BBC People's Choice Award for the second year running. In 2017, he was appointed to design an RHS/BBC Radio 2 garden for Chelsea with presenter Jeremy Vine. A contemporary space designed around the sense of touch, this immersive, tactile garden featured bold geometric forms juxtaposed with a soft, elegant planting palette.

Matt is now working on projects in the UK and Germany. His personable character and extensive horticultural knowledge ensure that he is a regular guest presenter and speaker at various garden design events and seminars.
