Hugh Macmillan was born on 4 June 1869 and had his early horticultural training at Dochfour Castle. He then moved to Wales where he worked under Andrew Pettigrew at Cardiff Castle. Around 1893 he went to Kew as a student gardener and gained experience in several departments. He left Kew in June 1895 to become Curator of the Royal Botanic Gardens, Peradeniya, Ceylon (now Sri Lanka), a position that he held until 1912 when he appointed superintendent of all gardens in Ceylon. Throughout his time in that country he contributed greatly to improving horticultural practices that were relevant to the whole region.
In 1910 he published Handbook of Tropical Gardening and Planting with Special Reference to Ceylon. It became a standard text, so successful that it went to a 5th edition by 1962. He also contributed articles to the Journal of Tropical Agriculture and to local newspapers. On retirement from this position in 1926 he moved to Persia (now Iran) and became Horticultural and Agricultural Advisor to the Anglo-Persian Oil Company based at Abadan.
Around 1928 Macmillan returned to Britain, settling at first in Ickenham, later moving to Ealing. He had joined The Kew Guild in 1895 and remained a member for almost 40 years. He was a Fellow of the Linnean Society from about 1920. In 1943 he was made an Associate of Honour of the Royal Horticultural Society.
