Juglans nigra Juglans

Juglans

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 have a sweet flavour, 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.

Juglans Growing Tips: The walnut family like deep, well drained soil and full sun or partial shade.
