Geilston Garden was founded in 1797, combining several features (traditional walled garden, kitchen garden, wooded area). The walled garden has a dominating 100-foot Wellingtonia (Sequoiadendron giganteum) in the centre of the lawn. The Geilston burn wends its way through the north of the estate towards the River Clyde in Cardross. The origins of the garden were most likely a result of the 1770 Montgomery Act, which saw the land around the house enclosed and planting undertaken.
Geilston was opened to the public with the death of the last resident, Margaret Bell, who was a friend of Elizabeth Hendry, the owner of Geilston who bequeathed the house to the National trust for Scotland and gave her friend life rent of the house. The Hendrys moved into Geilston as tenants but the family bought the house from the Geils in 1922. The garden as it appears today was mostly laid out by Elizabeth Hendry and Margaret Bell. A canon within the garden is said to have been a trophy from the Battle of Corunna brought to the Garden by Major General Geils, a previous owner of Geilston.
The kitchen garden is the most labour-intensive area. It springs to life in April with the first sowings of carrots, parsnips and beetroot closely followed by transplanted brassicas. Visitors can buy in-season produce from a small stand at the garden's entrance.
The walled garden is the focus of spring colour with azaleas, heathers and unusual shrubs such as Cornus kousa 'Satomi'. Summer colour is provided by the spectacularly vigorous species in the long herbaceous border –Thalictrum, Filipendula, Eupatorium, Helenium, Phlox and Sidalcea dominate the display.
The garden is open from March to October annually. The adjacent Geilston House is not open to the public.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
