Spectacularly situated beside the Salcombe Estuary, the garden at Overbecks enjoys a mild micro-climate which provides the ideal growing conditions for many tender plants. The garden is a series of enclosures and terraces laid out at the beginning of the twentieth century and subsequently planted with sub-tropical plants from around the world. An exotic note is struck right at the entrance by an avenue of Chusan Palms (Trachycarpus fortunei) which are also planted throughout the garden. The borders near the house contain South African plants, such as Crinum and Agapanthus and Echium pininana, with its incredible 16ft tall lavender-blue flower spikes.

The formal area of the garden is presided over by a bronze statue of a girl surrounded by four herbaceous borders which are a riot of colour in summer. Another small garden beyond looks down upon a parterre of dwarf box and coloured gravel, where orange and lemon trees in pots are placed in the summer and banana trees (Musa basjoo) grow throughout the year. Many tender plants add to the exotic feel though native wildflowers are not forgotten; in spring, bluebells, primroses, anemones and daffodils grow on the rough grass banks. The most spectacular sight in this garden is undeniably the flowering of the one hundred year old Magnolia campbelli; its deep pink blossoms making an exhilarating appearance in late Winter.
