The Black Walnut tree, Juglans nigra, is a large, fast-growing deciduous tree with distinctive ridged bark and butter yellow autumn leaves. It is a superb timber tree. Juglans nigra produces an abundance of nuts in the autumn (you will know that they are ready when you see lots of squirrels in your tree...). The nuts are notoriously messy to remove from their husks, but the quality of the kernel inside is generally considered to be better than the common walnut, which is the one you will normally see in the shops. Black Walnut trees can reach a height of about 30 metres. Standard trees are the largest size that we deliver; but we also sell younger Black Walnut saplings as well as Common Walnut trees.
Black Walnuts are an American tree that was brought to Britain in the mid-1600's by John Tradescant. They now grow wild in many parts of Southern England and Wales
How Standard Trees are Measured:
All our standards, are graded by their girth in centimetres 1 metre above ground level (basically, their trunk's waist measurement). They aren't measured by their height, which will vary. So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres around. This measurement makes no difference to the tree's final height. Standard trees are 3 - 5 metres tall (on average) when they arrive; they are the most mature trees that you can buy from us.
