Description
Any of several hardwood trees from the genus Populus. The trees are in the willow family and are found in temperate regions of the Northern hemisphere. There are four basic classes of poplar trees:
1) balsam poplar (cottonwood),
2) black poplar (English poplar),
3) white poplar (Populus alba)
4) gray poplar
5) trembling poplar (aspen)

It is primarily used for paneling, light construction, packing crates, cardboard and paper pulp. Poplar was frequently used in Italian panel paintings and for sculptures in southern Germany in the late Gothic period.
