About Juglans nigra 'Black Walnut'

Juglans nigra, known as Black Walnut, is a majestic deciduous tree valued both for its exceptional timber and its striking presence in the landscape. Growing 15–30 meters tall and wide, it features pinnately compound leaves that provide lush green shade in spring and summer, turning a beautiful yellow in autumn.

Its rounded canopy and straight trunk create a stately form, making it a magnificent shade tree for large gardens and parks. While prized by woodworkers for its dark, rich wood, the Black Walnut also adds natural beauty to outdoor spaces. It thrives best in full sun with well-drained soil and is drought-tolerant once established.
