pajukasvit

Pajukasvit, scientifically known as Salicaceae, is a family of flowering plants that includes willows, poplars, and aspens. These plants are typically woody, ranging from shrubs to large trees, and are commonly found in temperate and boreal regions of the Northern Hemisphere, often in moist environments like riverbanks and wetlands. The family is characterized by its simple, alternate leaves, which are often toothed. Flowers are usually unisexual and borne in catkins, which are pendulous or erect spikes of small, inconspicuous flowers.

The genus Salix, encompassing willows, is known for its flexible branches and characteristic weeping growth habit in some species. Populus, which includes poplars and aspens, is recognized for its fast-growing nature and often rounded or triangular leaves. Aspen species are notable for their ability to reproduce vegetatively, forming extensive clonal colonies.

Economically, pajukasvit are significant. Willow bark has been a source of medicinal compounds, most notably salicin, a precursor to aspirin. Poplar wood is widely used for pulp, paper, particleboard, and lumber. Certain species are also cultivated for ornamental purposes and for land reclamation due to their rapid growth and tolerance to various conditions. The family plays a role in supporting biodiversity, providing habitat and food for numerous insects and birds.
