GeneralitŠ°

The populus nigra is a deciduous arboreal plant with imposing dimensions native to Europe and western Asia, present in the wild also in the American continent. It has a round, domed crown, quite wide, but sparse, which quickly reaches 30-35 meters in height, it is not uncommon to see specimens of black poplar columnar habit; the leaves are alternate, dark green on the upper page and yellowish-green on the lower page, triangular or diamond-shaped, with the toothed margin. The bark is gray in young specimens, tends to darken with the age of the plant, furrowed by deep cracks. The male and female catkins grow on different trees, the female ones are white and cottony tufts of seeds, the male ones are gray, brown or reddish. It tends to develop long superficial roots. In America we also find P. deltoides, and in Italy and Europe P. alba is also widespread, with gray-green oval leaves. P. tremula, widespread in Europe, Africa and Asia, has rounded leaves that sway even with very light winds.


Exposure

The black poplar prefers very bright, sunny positions, but also adapts well to partial shade, does not like full shade. It does not fear the cold nor the wind, it is very resistant to pollution and is therefore widely used for road trees.

It can also grow spontaneously along the banks of the ditches or in flood areas.
