Lismore Castle
Jim Gardiner VMH
During the middle of March (2026), we visited Lismore Castle in County Waterford, the home of the Dukes of Devonshire since the end of the 18th Century and now the private family home of Lord and Lady Burlington. The gardens, covering 10 acres (4Ha) were only developed in the middle of the 19th Century with the help of Sir Joseph Paxton who created three distinct gardens, the Reilig re-opened in 2021, the Upper with its beautifully restored Paxton Vinery and the Lower Garden. And it was here our host Colm O’Driscoll, the Head Gardener lead us past a huge Magnolia delavayi planted against the Castle walls before descending into the Lower Garden, across the lawn and through the Yew Avenue before standing next to the largest Magnolia sprengeri I have seen, and it was in full flower!
