The original eighteenth century landscape of Saltram Garden has been enriched with later influences of shrub borders and fine specimen trees planted in spacious lawns. Paths lead back and forth along parallel lines, each revealing a special plant or glimpse of a building along its route. The Lime Avenue, which dates from the late nineteenth century, is under-planted with a succession of bulbs and wildflowers. A plethora of half-hardy shrubs and other plants grow amongst the glades, many of which it is rare to see growing outdoors in Britain. Examples include Hoheria 'Glory of Amlwch', Acca sellowiana, Loquat and the Cinnamon Suede trunked myrtle.

The impressive Orangery is home to potted citrus trees during the winter months which are moved outside to the Orange Grove (behind the Chapel Gallery) in May. The Mediterranean flavour here is enhanced with Chusan Palm, yucca and bottlebrushes, and there are also interesting Chilean specimens. At the far end of the garden is the Castle folly, which looks out over unspoilt views of the parkland, and also an impressive veteran oak tree, in which a tree house was built for the film Sense and Sensibility (1995).

Below the Orange Grove there is a recently replanted border designed by the late Graham Stuart Thomas, and adjacent to this an area of tender exotics. On the south side of the garden, beyond the Lime Avenue, is the Serpentine Walk with views out over the parkland. Planting here is themed especially for winter interest, mixed with areas of wild flowers and American prairie planting.
