White poplar tree is a deciduous tree (botanical name, Populus alba) native to the Eurasian region and grows up to a height of anything between 40 feet and 80 feet. The bark of the young white poplar trees is greenish-white and smooth and turns into gray and creased as they mature. The leaves of this species have a resemblance to maple leaves and are palmately lobed. Precisely speaking, the leaves of white poplar have an oval or spherical shape, having three to five lobes (each measuring five inches in length) appearing alternately. While the topsides of the leaves are glossy, deep green, the underside of the leaves are whitish as well as hairy. The leaves may also be bluish-green on the topside and wooly white in the underside. The leaves of white poplar have undulating edges and are roughly jagged.
Trees of this species bear male or female flowers (dioecious) separately. Each white poplar tree produces minute reddish male and green hued female flowers that emerge in detached clusters known as catkins on separate trees – male trees and female trees, in April (during spring) and prior to the emergence of the foliage. The clusters of white poplar flowers are not flashy or ostentatious. The blooms in the female catkins yield little capsules that are dehiscent (fruits that burst naturally) when mature and generally break open during the later part of May, scattering plentiful of seeds that are cotton-tufted. The fruits of white poplar are minute, while the seed pods have bristles that help them to disperse by winds.
The branches of white poplar are extremely vulnerable to break when they are under pressure, for instance when there is profuse snow or ice. Trees belonging to this species yield profuse root sprouts. And as mentioned earlier, white poplar trees are native to the Eurasian region and develop as well as thrive best when they are grown in areas receiving total sunlight.
White poplar is often cultivated as an ornamental tree mainly because its foliage, young branches, buds and even the young bark possess a silvery-green color. This species was introduced into North America for the first time during the mid-1700s and since then it has been grown extensively all over the United States. In fact, white poplar has also escaped cultivation and grows naturally in several regions, especially in the East.
White poplar is a deciduous tree whose growth is very rapid having a crown which varies from being asymmetrical to wide-rounded. The normal diameter of a mature white poplar is approximately two to three feet. Nevertheless, very often white poplar is seen growing as a multi-trunked tree. As in the case of American aspen, the leaves of white poplars also quiver even in slightest breeze, displaying its eye-catching foliage. However, the color of its foliage is very ordinary during the fall. The young white poplar trees have a smooth and greenish-gray bark, but it turns into deep gray-black with creases as it matures.
Going by ancient Roman mythology, it is believed that the white poplar was dedicated to Hercules since he had obliterated Cacus, an Italian shepherd who lived in a cave and thrived on human flesh, in a cave close to the Aventine Hill that was covered with white poplar trees. It is also said that when Hercules overcame Cacus, he made a crown using a branch of white poplar as a mark of his triumph. Since then, people who offered sacrifices to Hercules always wore a crown made with the branch of white poplar tree. Imitating Hercules, in those times, everyone who had magnificently defeated their enemies also wore garlands of white poplar branches.
White poplar belongs to the botanical family of Willow trees. Compared to many other trees, white poplar is reasonably hardy and has the aptitude to tolerate an assortment of soil as well as climatic conditions. Although, it is a very striking tree, often it might turn to be a bothersome tree owing to the littering of its fragile branches. While the white poplar may not be the most favoured tree to augment the beauty of a landscape, the bark of this tree possesses numerous remedial properties.

White poplar is often grown as an ornamental tree owing to its attractive foliage. However, white poplar is not a suitable tree to be planted along the streets because its roots are shallow and are likely to crumple the sidewalks damaging sewers. The suckering tendency as well as the cluttered propensities of white poplar, such as littering its brittle twigs, quivering leaves and cottony seeds also makes this tree inappropriate for growing in lawns. On the other hand, the rapid growth rate of white poplar makes this species an interesting option for being used as a windbreak or screen in the case of property lines. White poplar is an excellent species for growing in sunny woodlands where it may grow naturally. Commercially, all-male or seedless and columnar/ conical cultivars of white poplar are available easily. The wood of white poplar is soft and ideal for making cellulose as well as inexpensive boxes.
Habitat and cultivation
White poplar is indigenous to the Eurasian region, especially the area extending from Spain and Morocco via central Europe (i.e. northwards to Poland and Germany) towards central Asia. This botanical species grows best in damp locations, generally along water bodies, in the regions having hot summers and cold to gentle winter conditions.
For proper growth, white poplar needs enough of light and dampness. Trees of this variety are able to endure flood water as well as somewhat acidic soils effectively. While the greenish-white leaves of white poplar render it to be a useful ornamental tree, the sucker roots of the tree are likely to create problems in a number of conditions. When grown in open spaces like water meadows white poplar is extremely appealing and owing to its widespread root system as well as its ability to endure salty conditions, this species may also be grown along the coastal areas with a view to fortify the coastal sand dunes.
