Plant Common Name

Butternut

General Description

A fine hardwood tree, butternut is most revered for its fall crops of nuts with oil-rich, edible nutmeats that have a buttery texture and sweet flavor. It also has fine wood, which is hard, slow to rot and valued for furniture making and wood carving. This medium-sized deciduous tree is native to the northeastern quarter of the United States and the far southeastern section of Canada. It develops a broad crown comprised of upright, somewhat sparse branches and is slow growing.

Its compound foliage is made up of 11 to 19 leaflets. Each dark green leaflet is long, lance-shaped and fuzzy with tiny teeth along the edges. As the foliage emerges in mid to late-spring, separate male and female flowers appear along the branches. The male flowers, called catkins, dangle downward and are followed by small spikes of greenish yellow female flowers. The male and female flowers do not tend to bloom together on the same tree.

The fruits mature in late summer or fall. These are greenish yellow, fuzzy, oblong and heavy, so beware walking under the canopy of these trees when the fruit begins to drop after leaf fall. The nuts are surrounded by a fragrant, green fruit husk that is is leathery and sticky. The nuts underneath are protected by a hard shell that can be broken open to reveal the sweet nutmeats that are deliciously edible. Fall foliage color is yellow and the winter bark is gray, ridged and furrowed with diamond-like patterns.

This is an upland tree that is adapted to fertile soils with excellent drainage. In the wild, it can often be found growing along rocky outcrops and slopes and is not too pH sensitive but does tend to favor alkaline soils. Butternut requires full sun for best growth and nut production. It is a good tree for wildlife and naturalistic plantings on parks or campuses and may also be grown as a nut tree. This is not a good tree for manicured gardens or highly trafficked areas because of its heavy nuts stain and litter sidewalks and can put dents in cars.

Butternut is short-lived and rarely exceeds 75 years of age.
