Two acres of Hydrangeas border the banks of Mallard Pond and are mirrored in its tranquil water.
Most common are 'Mop-head' Hydrangea macrophylla and their vibrant 'Oxford and Cambridge' blue colouring is due to Trebah's rich acid soil.
The hydrangeas at Trebah were planted in the 1950s and the cut blooms were sent to Covent Garden flower market to raise income for the garden. The plants are now over 50 years old but continue to bloom beautifully year upon year.
It takes the gardeners about three weeks to prune the Hydrangeas in March and it is this careful cultivation that promotes the large flower heads and new vigour at the base of the plants.
