Thenford Arboretum has something for every gardening enthusiast. The arboretum, now spread out over seventy acres, features a collection of more than three thousand different trees and shrubs, together with extensive herbaceous borders, water gardens, an alpine trough garden, a sculpture garden, a rose garden and a rill.
• The Walled Garden – From sad neglect to two acres of magnificence, where the formal setting features fruit cages, herb garden, aviary, mirror pools, domes, a cottage ornée, and a spectacular fountain.
• The Rill attracts much attention…the visual impact, the magic of the glittering sparkle, the splash and gurgle, the drama of shape and sound, are indispensable.
• The Water Gardens – Water is the making of the garden: your own nature reserve, a personal therapy, every note inharmony with its background, a mirror for the things you’ve planned.
• The Sculpture Garden – Preparing the site and designing an outdoor sculpture gallery where the theme is ‘Modern British’ but a monumental Lenin tends to shock and surprise.
• The Trough Garden – A trick of the mind inspires a unique garden where wisteria, rhododendrons, alpine perennials and rare species provide year-round interest and immense pleasure.
Thenford Arboretum is open to visitors on 19 days a year, starting from Snowdrop days, right through to October.
