Juglans cinerea

Butternut is a tree that is widespread but seldom common in the upland deciduous forests of southern Ontario. It is a medium sized tree that is not tolerant of shade. It is sometime also known by the name of White Walnut. Leaves are compound and the fruit is an oval nut with jagged ridges. The nuts are eaten by a variety of wildlife and humans as well. Butternut will hybridize with several other related species including Japanese Walnut and Manchurian Walnut. Some hybrids are prolific nut producers and have been planted in yards or orchards for nut production.

Survival of Butternut is threatened by a disease called Butternut Canker. As a result, Butternut is listed as an Endangered Species.
