From WikiMD's Wellness Encyclopedia

Juglans is a plant genus of the family Juglandaceae, commonly known as the walnut family. The genus comprises 21 species of deciduous trees, which are native to the temperate zone of the Northern Hemisphere.

Description[edit | edit source]

The trees of the Juglans genus are large, typically 10–40 m tall. The leaves are pinnate, with 5–25 leaflets. The flowers are catkins, produced in spring. The fruit is a large, rounded nut, surrounded by a green husk before maturity.

Species[edit | edit source]

The 21 species of Juglans are divided into four sections. Notable species include:

  • Juglans regia, the Persian walnut, which is the most widely cultivated species for its nut.
  • Juglans nigra, the black walnut, native to eastern North America and valued for its timber.
  • Juglans cinerea, the butternut, also native to eastern North America and threatened by a fungal disease.

Uses[edit | edit source]

Walnuts are cultivated for their nuts, which are used in cooking and baking. The wood of walnut trees is also highly valued for its density, grain, and color, and is used in furniture and veneer production.
