  • Glenarn: Glorious Gardens of Argyll and Bute

    Glenarn is a private garden initially made famous for its collection of species rhododendrons created by the Gibson family. Established in the 1920s on the structure of the original Victorian garden, it lies in a protected hollow with a steeply sloping glen running its length and providing shelter for large-leaved and tender rhododendrons. Early in the spring, tall Asiatic magnolias create dramatic interest while other plants such as crinodendrons, eucryphias and acers provide colour at different times. The large rock garden, now deer fenced, built round the old quarry and natural rock outcrops provides habitats for meconopsis, primulas, paeonias and many bulbs. Below the greenhouse there is a vegetable and fruit garden providing produce for the house. Work is continuing, clearing the west-facing bank above Sunnyside in order to plant a succession of deciduous azaleas.
