Fanci Walnut Trees

Fanci Walnut Trees

　　Walnut trees, also known as Juglans regia, belong to the Juglandaceae family. Varieties include wild mountain walnuts and artificially grafted, improved cultivars. Originally native to Central Asia, they are grown throughout China. Generally, improved cultivars are chosen for planting because they yield higher production, have thinner shells—commonly referred to as "soft-shelled walnuts"—compared to their wild counterparts. Wild walnuts, on the other hand, feature thicker shells, larger size, and richer oil content, giving them a stronger aroma, and are commonly known as "iron walnuts." Walnut trees can serve as protective forests for roadside greening; due to their tough, elastic wood, they are also a premium material used in industry. Walnut shells can be processed into artworks. Alongside almonds, cashews, and hazelnuts, walnuts are internationally recognized as one of the "four major nuts." Walnut trees thrive in ecological environments with deep, loose, fertile, moist soil and a mild, cool climate.
