Hillier Nurseries and Garden Centres has announced the passing of John Hillier – a respected plantsman, devoted family man, and beloved figure in the horticultural world.

Born in Winchester as the eldest son of Sir Harold Hillier, John grew up surrounded by plants and the family’s horticultural legacy. Wartime relocation to Devon, his mother’s birthplace, left a lasting love for the South Hams, where he returned yearly. At 17, the family moved to Jermyns House, where his father developed the renowned Sir Harold Hillier Gardens. John's sporting spirit remained strong; he played hockey for Winchester and excelled in rugby and cricket in his school years.

After working briefly in the family business, John served National Service in Libya before gaining experience in U.S. nurseries, including Monrovia in California. There, he observed pioneering container plant production - knowledge that helped modernise Hillier Nurseries on his return.

John’s long association with the RHS Chelsea Flower Show began in 1958. Over 60 years, he led Hillier’s award-winning exhibits, achieving an astounding 74 consecutive Chelsea Gold Medals.

A chance encounter led him back to Valerie Barlow, a childhood acquaintance. They married in 1962 and raised four children together.

At Hillier Nurseries, John managed production and despatch before co-leading the company with his brother Robert. He skilfully balanced commercial needs with his love of plants, refining the range to meet modern gardeners’ needs while supporting the introduction of new, reliable varieties.

His passion extended nationally. He joined RHS committees, helped judge Wisley Trials, and advocated for the RHS Award of Garden Merit as a trusted guide for gardeners. He was also a regular judge at RHS shows and served as President of Plant Heritage Hampshire, promoting garden plant conservation.

Internationally, John travelled widely with groups like the International Dendrology Society, exploring native habitats and retracing the paths of legendary plant hunters. He worked closely with Roy Lancaster on later editions of the Hillier Manual of Trees and Shrubs, a staple reference for gardeners.

In recognition of his contributions, John was awarded the RHS Victoria Medal of Honour in 1996, following his father and grandfather’s achievements to receive the Society’s highest accolade.

John retired from the Hillier board in 2018 at the age of 83. He was a devoted husband to Val, proud father of Pepe, Andrew, Martin, and James, and loving grandfather to nine grandchildren. He treasured his faith, time with his family, his own garden and daily walks in the arboretum where his passion for plants thrived.

John Hillier leaves behind a legacy rooted in knowledge, kindness, and horticultural excellence. He will be deeply missed by all who knew him.
