Juglas regia

About

Common Walnut is a tall tree which has been widely planted in towns. It produces a large, brown nut, which we are all familiar with, but which is actually housed within a green husk.

How to identify

Common Walnut is most easily recognised in the summer and autumn when the large, round, green nuts appear. Its leaves are divided into seven to nine leaflets.

How can people help

The green space and plants in our towns and gardens can provide habitats for all kinds of wildlife. Try planting native shrubs and trees to encourage nesting birds, feeding mammals and invertebrates into your backyard. To find out more about wildlife-friendly gardening, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
