Geilston House, Gardens and Estate were gifted to the National Trust for Scotland in 1989 by the previous owner, Miss Elizabeth Hendry.
The Garden dates back over 200 years, and features a walled garden with a huge Wellingtonia (Sequoiadendron giganteum) on the lawn. There is a 40m long herbaceous perennial border, and a contrasting woodland area leading to the Geilston Burn.
There is also a demonstration kitchen garden with vegetable and fruit produce usually for sale during the growing season.
The garden enjoys the support of the Friends of Geilston (FoG), a membership organisation set up to promote, protect and preserve Geilston Garden, House and Estate in Cardross, as an NTS property, to benefit the local community and visitors from further afield.
