Juglans regia – Common Walnut Tree
Juglans regia – Common Walnut Tree
Common Walnut (Juglans regia) is one of Britain's most majestic and rewarding specimen trees — a slow-growing giant that rewards patience with decades of dappled shade, striking architectural form, and an annual harvest of rich, flavoursome nuts.
Imagine the scent of warm walnut leaves on a late summer afternoon, the satisfying crack of a freshly harvested shell in autumn, and the golden canopy that transforms your garden each October. This is a tree planted not just for today, but for generations.

Planting Advice
Plant in a generous hole with well-rotted organic matter. Stake firmly for the first two seasons. Avoid planting near vegetable beds — walnut roots produce juglone, which can inhibit some neighbouring plants. Water well during the first growing season to establish a strong root system.

Wildlife & Ecological Notes
Catkins provide early pollen for bees in spring. The walnut crop is eagerly taken by squirrels, jays, and other wildlife in autumn. The broad canopy supports a wide range of invertebrates, attracting insectivorous birds. Deep fissured bark provides habitat for beetles and other invertebrates. As a large long-lived specimen, it contributes significant ecological value over generations.
