Hidden Valley Gardens, Treesmill and Tregrehan, St Austell

Tuesday, June 30, 2020 12:01 AM

Hidden Valley Gardens offer colourful, cottage-style planting across 3.5 acres in a secluded valley. Beds and borders are crammed with herbaceous perennials, shrubs and grasses. There is a potager for vegetables, herbs, soft fruit and cut flowers. This RHS Partner Garden, with several awards to its name, also provides diversity with a large wildlife pond, Japanese and Mediterranean areas, and a fernery.

Historic, family-run Tregrehan has an enviable location for a woodland garden at the head of St Austell Bay. Towering conifers from the early Victorian plant hunters combined with botanically-important recent planting result in more than 150 trees of champion status. This garden is a delight at any time. The old grain mill, walled garden and magnificent glasshouse are also wonderful spaces to enjoy.

The booking form will be available in March 2020.
