About the garden

Owned by
Michael Burke

Blessed with a sub-tropical climate and situated on Scotland’s Garden Isle, Ascog Hall includes a climate change biotope, a plant hunter trail, architectural features and flora too numerous to mention; it is truly a gardener’s paradise.

The most outstanding feature of this three-acre garden is the Victorian Fernery, a beautiful sunken structure fed by natural spring waters and housing many fern species, including a 1,000-year-old Todea barbara (king fern) – the only survivor from the original collection. Unusual and exotic perennials, shrubs and trees – from the blue Meconopsis varieties to the fiery red Embothrium coccineum (Chilean fire bush) and the purple display of the Dactylorhiza purpurella (northern marsh orchid) – await the observant visitor in this sheltered garden, while all visitors will enjoy the display of seasonal colours in the various garden rooms.

An additional garden feature is the now accessible stables and coach house ruins, providing a reminder of long lost times. Established in 1875, the garden has been undergoing continuous restoration and improvement work since 2014.
