Developed over three generations of the Cox family, Glendoick is world‑renowned for its rhododendrons, azaleas, magnolias, and other acid‑loving plants, many grown from seed collected on plant‑hunting expeditions to the Himalayas, China, Turkey, and North America. The garden began in the early 1920s when Euan Cox returned from travelling with the great plant hunter Reginald Farrer and began planting seedlings in a sheltered glen; his son Peter continued the tradition, travelling extensively and introducing new species, while also breeding outstanding hybrids. The woodland garden is designed around the natural contours of the land, with drifts of rhododendrons flowering from early spring to early summer, their blooms ranging from the palest white and yellow through pink and red to deep purple — a living museum of botanical exploration and cultivation that remains one of the great rhododendron gardens of the world.
