Black Walnut trees are one of the scarcest and most coveted native hardwoods. Why not grow your own?! Sought after for the both their edible nuts, and wood, this tree grows to about 75 feet (and sometimes up to 100 feet). Yellowish green flowers bloom in late spring. Walnuts (Juglans sp.) are monoecious, which means the male and female flowers grow on the same plant but are separate. The female flowers give way to edible nuts. It will take 8 to 10 years for a seedling to start producing nuts. The green leaves are strongly aromatic when crushed, and turn yellow in the fall. This rugged, deciduous tree will be a regal addition to your landscape.
