Black Walnut Tree (Juglans nigra) is a stately deciduous tree in the walnut family (Juglandaceae), native to North America and admired for both its rich, flavorful nuts and its exceptionally valuable timber. In Ireland, it grows steadily in fertile, well-drained soils and can become a magnificent long-lived feature in agroforestry systems and large gardens.

Growing Instructions
Maturing to heights of 25–35 metres, the black walnut develops a broad, rounded crown and deep root system. Its dark, deeply ridged bark and elegant pinnate leaves make it striking in all seasons. After 10–15 years, mature trees begin producing heavy crops of nuts encased in thick green husks, ripening in late autumn. The kernels are prized for their distinctive, earthy flavour and high nutritional value.
Black walnut thrives in full sun and prefers deep, loamy soils with good drainage. It is drought-tolerant once established but appreciates moisture during its early years.
While it produces juglone, a natural compound that can inhibit some plants, many woodland and meadow species coexist happily beneath it when designed thoughtfully. A long-term investment in food, beauty, and carbon storage, the black walnut is a legacy tree for regenerative landscapes.
