About the garden

Upton Castle Gardens is a privately owned, historic garden. The medieval castle remains a family home. It provides a spectacular setting for terraces of herbaceous borders, a traditional rose garden, a Georgian walled garden and the more intimate chapel surroundings. The gardens extend into the less formal plantings of a deeply wooded valley, which sweeps down to the Cleddau estuary. 

The sheltered, warm maritime climate allows various plants and trees to thrive. Woodland walks lead through the dappled light of ancient trees to salt marshes. The arboretum features magnolias, camellias and rhododendrons. It also features champion trees. 

The 1.3-acre walled garden showcases fruit and vegetables in a long-established kitchen garden setting, providing fresh produce for the café and the castle. A newly planted orchard and adjacent border have been designed to attract bees, butterflies and other pollinators. The traditional cut-flower bed features roses, sweet peas, dahlias and zinnias, adding vibrant splashes of colour throughout the garden.
