PETER A. COX
Rhododendron Expert, Plant Hunter, Nurseryman, Glendoick Garden Centre founder, Author and Plant BreederBorn 28th February 1934 Died 8th April 2025
"Peter Cox was born in February 1933 in Dundee Scotland. His father Euan Cox was a well-known horticultural writer and plant-collector who owned a garden at Glendoick, Perth, Scotland.
• After studying horticulture at college in Edinburgh and working for a year at Notcutts Nurseries, Woodbridge, Peter and his father Euan founded the rhododendron nursery ‘Glendoick Gardens Ltd’ in 1953.
• Peter married Tricia Sherrard in 1963. They met when she came to buy rhododendrons for her family garden, Maryborough House, Cork Ireland. Their sons Kenneth (born 1964) and Raymond (born 1966) and their parents lived at Sandyhall farm across the fields from Glendoick. [ Tricia Cox (née Sherrard), founder/owner of Glendoick Garden Centre with her husband Peter Cox, died peacefully at Glendoick on 2 nd May 2020.]
• In 1972 Glendoick Garden Centre was opened, largely under the management of Tricia Cox while Peter ran the nursery. Over the years Glendoick became a centre for excellence in all aspects of the culture of, hybridising of and publishing books on rhododendrons.
Peter Cox Plant HuntingPeter Cox has probably seen and studied more species of Rhododendron in the wild than any one else at any time. Peter and his best friend Sir Peter Hutchison went on 18 major plant-hunting expeditions and his eye for good garden plants brought back from his travels range from Ulex gallii Mizen from S. Ireland to Rhododendron coxianum which he discovered in India in 1965. He has collected thousands of seed numbers from many parts of the globe, all carefully documented as to altitude, aspects, growing conditions etc. Both the seed itself and many plants grown from it have been distributed to Botanic Gardens and collections in many countries. Cox and Hutchison, one of the world’s most durable plant hunting partnerships, returned to China, Tibet, or the Himalaya almost every year, until they retired to write their memoirs the mammoth book Seeds of Adventure.
Peter Cox Plant BreederOne of the most successful and important rhododendron hybridisers, in the 1960s Peter Cox that the future lay in developing cultivars for the small garden. His dwarf rhododendron hybrids were named after birds such as ‘Chikor’, ‘Curlew’ and ‘Ptarmigan’ and his evergreen azaleas named after animals, such as ‘Panda’ and ‘Squirrel’. Hybridising in the 1980s focussed on rhododendrons with coloured foliage and new colour breaks. Compact Hybrids Wine and Roses ['pinkros'] and Evered ['85/1C'] are protected by Plant Breeders rights and have become best sellers worldwide.

Peter Cox wrote 13 books (see section below) and wrote 100s of articles for specialist publications, Country Life and many other journals.
Peter Cox GardenerPeter Cox created two woodland gardens, one at Glendoick, Perth and another, Baravalla, three hours away on the west coast of Scotland which he created with best friend Peter Hutchison. At Glendoick, Peter Cox was to be found most days, weeding, watering, planting, pruning and bellowing at errant labradors. He carried on gardening well into his 80s. His son Kenneth is trying to look after all the things he planted...
Peter served for many years on the Gardens Committee of the National Trust for Scotland and on the Board of Trustees of the Dundee Botanic Garden. Peter Cox was a modest and shy man, who had a pronounced stammer and preferred to be gardening at Glendoick or climbing Chinese mountains in search of plants to being the centre of attention. And yet he truly was the world’s ‘Mr Rhododendron’. It is doubtful that anyone has ever known as much or achieved so much in this field and it is doubtful anyone ever will.
Peter & Tricia Cox celebrated their golden wedding in 2013. Peter loved dogs, (black labradors), table tennis, bridge, shooting, wild birds, cricket and talking horticulture and plant hunting with fellow enthusiasts.
Peter Cox died on 8th April 2025. aged 91."
The EHM Cox trophy is awarded at the Perth SRGC Show and it has been the honour of Ian and myself to win this trophy on a number of occasions. We first met Peter Cox when introduced to him by the famous plantsman Roy Lancaster many years ago - and we greatly appreciated their continued friendship.
