Juglans nigra
Black walnut

One of the last trees to leaf out and one of the first to lose its leaves, the black walnut is a highly prized species in the veneer industry, being used for the manufacture of furniture and gun stocks. This species is allelopathic in nature, secreting a chemical known as juglone through all portions of the plant, killing most plants that grow around (especially members of the Rosaceae family). Although messy, the slightly bitter nuts are well worth the effort of opening and eating.

Size:75-100' high (150' possible)
Color:Dark green
Texture:Medium in leaf, medium-coarse in winter
Hardiness:Zone 4b USDA
Habitat:Vermont - Florida - Texas - South Dakota
Family:Juglandaceae
