John Medhurst designed Trinity’s gardens, based on plans drawn up by US landscape architect Lanning Roper. Upon the architect’s death, Medhurst completed the project in 1983. Little of the garden pre-dates 1983 except hedges and trees, notably a purple beech planted in 1981 by the late Queen Mother. An old mulberry, plane, horse chestnut and a swamp cypress give maturity to the garden, while cherries add colour. A new in-patient centre opened in 2009, requiring more work on the garden. TP Bennett designed the newer parts to enable viewing from the centre’s upper and lower levels, with steep slopes of shrubs and herbaceous planting falling towards the building. A weeping cherry, planted to mark the opening, sits in the middle of one of the lawns. In 2012, 2015 and 2016 the garden won the London Gardens Society Hospice Garden Plate.
