Black Walnut Tree Whether for Taste or Timber, Black Walnut Trees have it all. Can't decide between a tree known for its fine wood and a fruit bearing tree with a healthy harvest?The Black Walnut will give you all that and more. A wide-branched tree reaching heights between 70 and 150 feet, the Black Walnut does well in open fields, on sloped land and a diversity of planting sites so long as the soil is well drained and nutrient dense. The beautiful dark brown color of its bark makes black walnut wood the most sought after wood in the world. The tree's nickname, 'American Walnut' is no fluke. Our forefathers adorned their homes, crafted barns and built fences with wood made from the black walnut. The leaflets, as large as some trees leaves, are dwarfed by the leaves themselves, which can grow up to a mammoth two feet long. And let's not forget the nut. The thick, black husk that gives the tree its name serves as ample protection for a round, savory fruit packed with flavor. The tree yields a nut so rich and delicious, it can be enjoyed right out of the shell, baked in deserts or crushed and topped on your favorite ice cream. With an abundant autumn harvest, a single tree can produce hundreds of nuts in just one season. Mature Height: 70-150 ft. Mature Width: 30-40 Sunlight: Full Sun Spacing: 30-50 ft. Growth Rate: Moderate Drought Tolerance: Good Harvest Time: September - October Fruit Color: Green husk Year to Bear: 8-10 years Chill Hours (minimum): 600-700 Botanical Name: Juglans nigra
