Black walnutOne 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.| Habit: | Rounded, with sparse branching, lower branches become pendulous and droop downward, nearly touching the ground | | 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 | |
