Description
It is a medium-sized , growing to heights of up to (rarely more), with a trunk up to in diameter and a broad, rounded crown. The bark is smooth and greenish-white to greyish-white with characteristic diamond-shaped dark marks on young trees, becoming blackish and fissured at the base of old trees. The young shoots are covered with whitish-grey down, including the small buds. The are long, five-lobed, with a thick covering of white scurfy down on both sides, but thicker underneath; this layer wears off long, produced in early spring; they are , with male and female catkins on separate trees; the male catkins are grey with conspicuous dark red stamens, the female catkins are greyish-green. The female catkins lengthen to after pollination, with several green seed capsules, maturing in late spring to early summer. It also propagates by means of growing from the lateral roots, often as far as from the trunk, to form extensive .Flora of NW Europe: Populus alba


Hybridization
White poplar hybridizes with the closely related common aspen ; the resulting hybrid, known as grey poplar ( Populus × canescens), is intermediate between its parents, with a thin, grey, downy coating on the leaves, which are also much less deeply lobed than white poplar leaves. It exhibits marked , reaching tall and a trunk diameter over , much larger than either of its parents. Most grey poplars in cultivation are male, but female trees occur naturally and some of these are also propagated.


Cultivation and uses
The wood is soft but close-grained and easy to carve, shrinking very little during seasoning. It has been used for sculpture from Europe to China and the US.Rösch, Petra, Chinese Wood Sculptures of the 11th to 13th centuries: Images of Water-moon Guanyin in Northern Chinese Temples and Western Collections, pp. 179-180, 2007, Columbia University Press, , 9783838256627; [4] The Penitent Magdalene by is one 15th-century example.

It was the most commonly used wood for in Italy throughout the Middle Ages and Renaissance, until mostly replaced as a matrix by from 1500 onwards. Most earlier Italian Renaissance paintings are painted on poplar panels, the being but one example.

White poplar requires abundant light and ample moisture, and stands up well to flood water and slightly acidic soils. Its green-and-white leaves make it an effective , but the root suckers may cause problems in some situations. It is very attractive as an open-grown tree in water meadows, and because of its extensive root system and tolerance of salt, is also planted to strengthen coastal .Vedel, H., & Lange, J. (1960).

Americas
White poplar was first introduced to North America in 1748 and has a long history in cultivation. It is now found in 43 states throughout the contiguous U.S. It has come to be considered weedy or ; it has been banned in Connecticut and is the most common introduced tree species on Cape Breton Island.Keeler, H. L. (1900). Our Native Trees and How to Identify Them pp. 428–432. Charles Scribner's Sons, New York US invasive state location map

In US intensive forest management, it is being replaced by various Populus sect. Aigeiros hybrids. The wood is soft, and used for cellulose and to make cheap boxes.

It also grows in the temperate zones of South America. Mainly in Chile, Argentina and Uruguay A conical from , Populus alba 'Pyramidalis' (Bolle's poplar; syn. P. bolleana) is sometimes planted in parks.


History
