Each of the trees in this stand is a genetically identical male that has reproduced vegetatively. Although no single tree in this stand is of that age, the stand itself as a single organism has existed that long. [120] Individual trees in the clonal patch have been listed as having ages of 2000 [121] [122] or even to 3000 years old. [123] [124]
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
Hardwood from North American trees has a variety of commercial uses, including in furniture, carpentry, tools and musical instruments. Some timber is milled for plywood, wood veneer and construction framing, including structural support beams and studs. Logs can be fashioned into posts and poles.
Umbellularia californica is a large hardwood tree native to coastal forests and the Sierra foothills of California, and to coastal forests extending into Oregon. [2] It is the sole species in the genus Umbellularia. The tree's pungent leaves have a similar flavor to bay leaves, though stronger, and it may be mistaken for bay laurel.
Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a tree stops growing.

A mature tree. Populus deltoides is a large tree growing to 20–30 m (65–100 ft) tall and with a trunk up to 2.8 m (9 ft 2 in) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. Bark of a mature tree
The American basswood is a medium-sized to large deciduous tree reaching a height of 18 to 37 m (60 to 120 ft) exceptionally 39 m (128 ft) with a trunk diameter of 1–1.5 m (3–5 ft) at maturity. It grows faster than many North American hardwoods, often twice the annual growth rate of American beech and many birch species. Life expectancy is ...
