Born in Malta in 1935, Cyril has been a plantsman all his life. Starting 'under glass' at 13 years old, growing cucumber and sweet peas. Tending the plants at a local nursery, he went on to gain his first RHS examination at 16. After National Service he studied at the Hampshire County Farm Institute at Sparsholt gaining distinction in his National Certificate of Horticulture and being awarded the Landsman Book Award for Meritorious Work.

At the age of 22, with a young wife, Cyril travelled to Nyasaland, now part of Malawi, to strengthen the production of fruit and coffee plantations.  Civil unrest made the post challenging yet that didn’t stop him, at short notice, creating a garden for the visit of the Queen Mother.  An area of bush land was transformed into a flowering garden fit for a royal garden party. It even contained the standard rose ‘Queen Elizabeth’ in her honour.

Studying at the Royal Botanic Gardens, Kew followed.  Cyril was paid eight pounds a week and topped up his income by maintaining the garden of the wife of Henry Ridley, a former Director of the Botanical Gardens in Singapore and the pioneer of Malaya’s rubber industry.   Little did Cyril know then that he would soon be the senior assistant manager of a 5,000 acre rubber plantation and collecting live specimens of the flora to send to Kew!

Arriving in Kota Kinabalu, Borneo on New Year’s Day 1963  a new adventure awaited Cyril and his young family.  The Sapong Rubber Estate near Tenom in Sabah became their home which was surrounded by the rubber tree Hevea brasiliensis.  The rubber trees were planted on flat ground and terraces with legumes planted on terrace faces to prevent erosion.  Cyril worked with the rubber research station to increase the rubber yield by budding selective clones.  He became a ‘jack of all trades’ – he oversaw a workforce of over a 1,000 to grow rubber trees, tap the trees, collect the latex, turning the latex into rubber sheets and then export it.  It was a busy and fulfilling role.

Cyril was asked to collect living species and send them to RBG Kew .  He collected from the local area and especially enjoyed plant hunting expeditions with his great friend Keith Wooliams, to the rainforests of Mount Kinabalu. There they found ‘a plantsman’s paradise – so many orchids, epiphytes, pitcher plants and ferns.’ The range of plants collected was diverse, from water lettuce to dwarf banana to rhododendron to fern to orchid. The plants were cleaned, labelled with name and number and then sent back to RBG Kew with detailed collecting notes.  Many of the hundreds of plants collected were grown on at RBG Kew and some species, including the Asechynanthus tricolor and Rhododendron praetervisum shared with RBG Edinburgh.  One of the plants, the epiphyte Rhododendron orbiculatum, was written about and published in Curtis’s Botanical Magazine (CLXXV111, Part 1 , July 1970).

Cyril collected many very rare species of orchids which, although previously known to RBG Kew, had never before been seen as living specimens.   In March 1965 he collected an orchid from the forest floor close to the Sapong Estate. This was found to be the only known specimen of the orchid named, in 2000,  Kuhlhasseltia gilesii Ormerod

Cyril can share many stories of life in a tropical rainforest with three children under four.  From how to sterilise water, to teaching children how to stay safe from the spitting cobras on the wooden beams under the house or being marooned in the house for three weeks when the Padas river flooded! 

From Borneo, Cyril and his family moved to Aden from where Cyril worked in the Yemen, Bahrain and  a number of desert stations supporting the development of irrigation systems.  After being evacuated due to unrest the family moved to Malta for three years. Cyril was instrumental in kick-starting the planting of woodland on previously bare land and was presented with the ‘Men of the Trees’ Gold Medal  by the Agricultural Minister in recognition of the positive impact on the landscape. 

In later years Cyril worked for the Department of the Environment in the UK and Gibraltar.

In retirement he has enjoyed acting as a consultant  for exhibits for the Chelsea Flower Show where the displays, on both occasions, received a Gold Medal.  For many years he has shared his knowledge of plants through being a judge at local horticultural shows and giving talks about his life as a plantsman.  He has now slowed down and currently enjoys garden shows on the television and spending time with his family.

A story behind every plant

“Every wild collected plant in the huge living collection at RBGE comes with a story. Of course, some are more interesting than others…


In 2014 Katherine Dixon contacted the Garden and enquired after collections made in the 1960s in Borneo; these collections were made by her grandfather, Cyril Giles, along with the late Keith Woolliams.”
