Black Walnut
FamilyJuglandaceae
Juglans nigra is an imposing and majestic ornamental tree, better known as the black walnut, valued for its rich green foliage that creates dense, structured shade, ideal for large gardens, parks, or open landscaped areas. Its rounded, spreading silhouette provides a balanced and elegant presence, while its edible (hard-shelled) nuts offer an additional point of interest for harvesters. In autumn, the foliage turns warm yellow hues, adding a colorful dimension to the colder season. Very hardy and robust, this tree prefers a sunny to semi-shady exposure and fertile, deep, well-drained soil to fully develop its potential. Juglans nigra combines dark foliage, imposing structure, and practical use, making it an excellent choice for any large landscape planting.
