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. In general, poplar is a soft, lightweight wood that is easy to work. The wood has a fine, uniform grain but it is prone to warping. 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.

1) Balsam poplar (Populus balsamifer or Populus tac a ma haca)
2) Cottonwood (Populus deltoides)
3) English poplar or black poplar (Populus nigra)
4) Gray poplar (Populus x canescens)
