The
Butternut (
Juglans cinerea), also occasionally known as the
White Walnut, is a species of
walnut native to the eastern
United States and southeast
Canada, from southern
Quebec west to
Minnesota, south to northern
Alabama and southwest to northern
Arkansas. It is absent from most of the
Southern United States. It is a
deciduous tree growing to 20 m tall, rarely 30 m, and 40-80 cm stem diameter, with light gray
bark. The
leaves are
pinnate, 40-70 cm long, with 11-17 leaflets, each leaflet 5-10 cm long and 3-5 cm broad. The whole leaf is downy-pubescent, and a somewhat brighter, yellower green than many other tree leaves. The
flowers are inconspicuous yellow-green
catkins produced in spring at the same time as the new leaves appear. The
fruit is a
nut, produced in bunches of 2-6 together; the nut is oblong-ovoid, 3-6 cm long and 2-4 cm broad, surrounded by a green husk before maturity in mid autumn. Butternut grows quickly, but is rather short-lived for a tree, rarely living longer than 75 years.
The Butternut is seriously threatened by an introduced
canker disease, caused by the
fungus Sirococcus clavigignenti-juglandacearum. In some areas, 90% of the Butternut trees have been killed. Completely free-standing trees seem better able to withstand the fungus than those growing in dense stands or forest. The fungus is spread by a wide-ranging vector, so isolation of a tree offers no protection.
Uses
The nuts are usually used in baking and making candies, having an oily texture and pleasant flavor. The husks are also used to make a yellowish dye.
Butternut wood is light in weight and takes polish well, is highly rot resistant, but is much softer than
Black Walnut wood. Oiled, the grain of the wood usually shows much light. It is often used to make
furniture, and is a favorite of woodcarvers.
