Easton Lodge originally stood at the heart of a hunting forest, filled with historic oaks.
In Victorian times a wider variety of trees were planted. And while the giant redwood is not the biggest of its type, these days it towers over the car park entrance at the Gardens of Easton Lodge.
The Cedars of Lebanon, one of which was planted by King Edward VII, are probably as wide as they are tall.
On Sunday (August 22), visitors at the Open Day will be encouraged to look closely at the trees.
They include the young scarlet oak at the top of the Glade, the old red oak and Atlantic cedar at the bottom, the limes which line the walks around the treehouse, and the fruit trees in the walled kitchen garden.
