Juglans nigra Walnut

Description: Juglans nigra, also known as Black Walnut is a vigorous, large, deciduous, broad-crowned tree. The foliage, which is fragrant when crushed, is large, oblong and purple-green when young, turning to green in the summer and then yellow, bronze in the autumn. The tree’s seeds are edible and making them useful in confectionery. They are, however, not as easy to extract as those of the common walnut (Juglans regia).

History: Native to the Eastern and Central United States, Juglans nigra has been in cultivation since 1686. Received the Royal Horticultural Society's Award of Garden Merit.
