Winner of the Gardener’s World magazine ‘Gardens to Visit SW’ award 2010. The garden has been created over 40 years by the late Kenneth Ashburner, and now a charity has been formed to safeguard this unique collection of birch trees and alder trees.

Alders from this region include Alnus hirsuta, Alnus barbata, Alnus japonica, Alnus fauriei, Alnus sieboldiana and Alnus pendula. Rare birch such as Betula ashburneri and Betula chichibuensis.
