It has a good collection of rhododendrons, sorbus, alder, birch and tilia but also includes many unusual trees from around the world. The arboretum is zoned into geographic areas and species type. It includes a Japanese garden, bog garden, bog wood, loch and quarry garden. First created in 2005 and is ongoing. Most plants are grown from hand collected seed and propagated in the Georgian greenhouse.
Over half of the gardens are taking part to support open garden charity Scotland’s Gardens Scheme which raises money for hundreds of local charities.
