Trinity has extensive gardens, the most famous of which are permanently on view through the gates on Parks Road. They often appear in episodes of Inspector Morse and Lewis. Alongside the lawns are herbaceous borders which recently have been redesigned, with a move away from the traditional planting, to a border which is much more organic and naturalistic, comprising multiple layers of varying heights, linked by repeated themes. The plant palette is intended to provide colour, interest and texture throughout the year.
