Willow is divided into weeping willow and withered willow. Weeping willows, also called willows, are deciduous trees; Salix salicifolia, also known as Salix salicifolia, is a deciduous shrub. Willow branches are flexible, with long and narrow leaves, yellow-green flowers in spring, white hairs on seeds, and dancing with the wind when mature. Willow can reproduce asexually, with willow roots growing mainly. "Willows grow into flowers unintentionally", and its unparalleled adaptability makes it one of the most common tree species in China's land greening throughout the ages. Many fibrous roots are deeply rooted in the soil, extending in all directions, hugging the earth tightly, providing rich nutrition for the trunk. Willow is not as tall and straight as pine, nor as tall and straight as poplar. Branches usually grow in two or three meters from the trunk, and the smooth and soft branches droop like silk. Willow leaves are simple and alternate, and the leaves are long and narrow, but the width is suitable, which looks like a girl's slender eyebrows, just like "whipping face is like a willow eyebrow."
Willow is a native tree species in China. According to textual research, there are willows in Shanwang forest in Miocene of Tertiary. According to the sporopollen analysis in Qingdao, Shandong Province, "Salix plants existed near Jiaozhou Bay in Qingdao from1000 to 8500 years ago." Willow is also one of the earliest artificially cultivated and widely distributed plants in China, and the word "willow" has appeared in prehistoric Oracle Bone Inscriptions.
