Trinity College initiated a physic garden on the main College campus in 1687 to provide plant material to support the teaching of medicine. By 1773 this garden had become derelict and was partly used to dump offal from the Anatomy Department! There was a short-lived attempt to establish a garden in Harold’s Cross to the south west of the campus, but by 1806 the College Physic Garden was finally abandoned, and a botanic garden established in an area of land leased in Ballsbridge. Over the next one hundred years this garden developed considerably and held an important and varied collection of plants. Notable curators of this garden include J. T. Mackay, credited with producing the first flora of Ireland – Flora Hibernica – in 1836, and F. W. Burbidge, who was well known for his exploration of the Kinabalu region of what is now Sabah in the north of Borneo, and for his work on the collection and hybridisation of Narcissus.

The Garden celebrated the tercentenary of the College in 1892 with the presentation to the garden of a massive specimen of the tree fern Todea barbara, a gift from the Royal Botanic Garden Melbourne. A cutting of this plant still thrives in the present garden. The position of Curator was abandoned after the death of Burbidge, and as a result the garden ceased to develop. This was partly redressed with the appointment of an assistant curator in 1950. In 1965 a plan was put before the College Board to relocate the garden to Trinity Hall, a student accommodation complex in Dartry. This move was approved, giving the garden better long-term security as the Trinity Hall site is freehold. The move was completed over 1966 and 1967; a large hotel complex now stands on the former Ballsbridge garden site. Many important plant specimens were transferred to Dartry, including a 25-foot-tall Ginkgo biloba and various cycads.

After the move to Dartry, the development of the ‘new’ botanic garden proceeded steadily. An important development was the establishment of a position of Administrator in 1981 (now Curator/Administrator). The garden developed an international reputation for plant conservation work and supported a diversity of research projects ranging from low temperature tolerance to the effects of elevated carbon dioxide on growth of grasses. To commemorate the College quatercentenary in 1992, the garden was presented with the gift of another tree fern by the Royal Botanic Garden Sydney: a fine specimen of Cyathea australis from Australia.

A more detailed account of this period of the garden’s history may be found (here) in The Story of the Botanic Gardens of Trinity College 1687 to 1987 by Peter Wyse Jackson, published privately in 1987. An edited version was published as ‘The Botanic Garden of Trinity College Dublin 1687 to 1987’ in the Botanical Journal of the Linnean Society (1987), vol 95 pp 301-311.

The Garden Today


Today, the garden supports Trinity College Botany Department’s teaching in conservation biology, taxonomy, physiological ecology, pollination biology and plant response to climate change. It provides living plant material, controlled growth environments, glasshouses and other experimental facilities for botanical research. The garden also houses the Irish Threatened Plant Seedbank, circa 4000 species in the living collections, four heated glasshouses, three unheated glasshouses, walk-in controlled environment chambers, low temperature growth facilities, experimental plots including open top chambers, growing beds including systematic garden and arboretum, potting shed and ancillary facilities. Zoological facilities including research mesocosms and a bird house are also located within the gardens.
