This three-acre walled garden has a delightful collection of old-fashioned roses and fine herbaceous borders, and also houses the National Bonsai Collection for Scotland. A particular feature of the garden is the four 400-year old clipped yew trees. There is also extensive woodland for a peaceful stroll.

The 17th-century house situated in the garden was built for Sir James Murray of Kilbaberton around 1635. Its two Georgian reception rooms added in 1823 are opened by the Friends of Malleny on occasion during the summer.
