Butternut is a small to medium deciduous tree with most striking golden yellow foliage in autumn. It is also known as white walnut. It grows rabidly in well drained soils and the sweet nuts are highly liked by man and animals. The nuts have a strong aromatic flavor, thick shells and the highest protein content of all nuts, 75%. Butternut is short lived, seldom reaches the age of 80 but, it is the hardest of all walnuts and adaptable to many soil types and conditions.
The tree grows up to 25 meters high with a spread of 20 meters; it is self-fertile and grows best on stream bank sites. It flowers from late spring to early summer and the small, 3-6 cm in diameter oblong nuts are born in clusters of 3 to 5 and fall in autumn. Seeds are eaten raw or ground into a powder and used with flour to make biscuits and/or cakes. Edible oil is also obtained from the nuts. Commercial nut-bearing age begins at about 20 years.
Butternut is propagated from seeds in spring time and they produce a deep taproot but also outspreading. They are intolerant to root disturbance and shade. Stumps of young trees are also capable of sprouting. The tree grows fast especially as seedling. Butternut is the most cold-resistant of all walnuts tolerating temperatures to about -35C. Trees should only be pruned when they are completely dormant.
