Juglans regia

Juglans regia

Juglans regia is a long-lived deciduous tree valued for its delicious edible fruit and valuable timber. It is native to southwest and central Asia.

It grows to a height of 10–25 meters.

It forms a dense, broad, and spreading crown with a spherical shape and a low-set trunk.

The large, odd-pinnate leaves, composed of several leaflets, develop relatively late – only in May.

The flowers are dioecious, monoecious (male flowers in the form of hanging catkins, female flowers less conspicuous), appearing simultaneously with the leaves in May. The plant is wind-pollinated.

The fruit is a spherical drupe with a green, fleshy outer covering (green husk), which splits open upon ripening in autumn, revealing a hard nut with an edible seed inside.

Juglans regia grows best in fertile, deep, well-drained soil with an alkaline pH (pH 6.5–7.5).

It prefers a sunny location sheltered from strong winds.
