The Floral Clock 2026: Edinburgh
We are delighted to have been chosen as the organisation to be celebrated in the City of Edinburgh Council Floral Clock Display this year. As we reach our 20th anniversary, it is a fitting tribute to Trellis and our vital work to make excellent therapeutic horticulture and its benefits, accessible to all. The floral clock, which is a stunning piece of horticultural and engineering work, goes on display from June to October (weather permitting) in Princes Street Gardens in the centre of Edinburgh.
