Juglans nigra

Juglans nigra Details

Juglans nigra, commonly known as Black Walnut or Eastern Black Walnut, is a large, deciduous tree grown for its edible nuts. Leaves emerge a fresh green in spring, mature to dark green in summer, then develop colourful, yellow tones in autumn before falling. Small, yellow flowers in spring result in the tasty nuts in autumn. The nuts are initially enclosed in a tight green husk before opening and falling in autumn. This tree will grow to 25 m tall and 18 m wide and prefers a full sun position on a well-drained site. It is tolerant of cool climates, frost, and moderate wind, though shelter from wind is important while it is establishing. The Black Walnut is commonly included in large gardens as a specimen, grown as a shade tree, or simply planted for nut production.
