Poplar is generally planted for visual variation rather than being a commercial crop, although some varieties can outperform willow on suitable sites. [ 2 ] Species are selected for their acceptance of varying climate and soil conditions, relative insusceptibility to pests and diseases, ease of propagation and speed of vegetative growth.
Although the wood from Populus is known as poplar wood, a common high-quality hardwood "poplar" with a greenish colour is actually from an unrelated genus Liriodendron. Populus wood is a lighter, more porous material. Its flexibility and close grain make it suitable for a number of applications, similar to those of willow.
In the United States, it is commonly known as tulip poplar or yellow poplar, even though the tree is not related to the poplars. It is notable for its height, which can exceed 190 feet. The wood is very light, around 490 kg per cubic meter, [1] but very strong and is used in many applications, including furniture, joinery and moldings. It can ...
The wood is light yellow to brown, and the sapwood creamy white; light, soft, brittle, close, straight-grained. Specific gravity: 0.4230; density: 422 g/dm 3 (26.36 lb/cu ft). Winter buds are dark red, covered with a bloom, obtuse; scales becoming conspicuous stipules for the unfolding leaf, and persistent until the leaf is fully grown.
The selection of increasingly fast-growing cultivars has at least halved the revolution in poplar plantations.. Transgenic poplars are being or have been tested, in North America and in France in particular, with poplars intended for energy production and poplars potentially destined for the paper industry, [3] [4] as well as with short rotation coppice or very short rotation coppice, with ...
Populus balsamifera is the northernmost North American hardwood, growing transcontinentally on boreal and montane upland and flood plain sites, and attaining its best development on flood plains. It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found.
Populus trichocarpa, the black cottonwood, [1] western balsam-poplar [2] or California poplar, is a deciduous broadleaf tree species native to western North America. It is used for timber , and is notable as a model organism in plant biology .
Many of the cottonwoods grown commercially are the hybrid of eastern cottonwood and black poplar, Populus × canadensis (hybrid black poplar or Carolina poplar). Cottonwood bark is often a favorite medium for artisans. The bark, which is usually harvested in the fall after a tree's death, is generally very soft and easy to carve.
