The tree was introduced to the U.K. in 1853, and by now might have 5,000 mature trees growing there where it is more commonly known as Wellingtonia after the Duke of Wellington. The giant sequoia grow to an average height of 50–85 m (164–279 ft) with trunk diameters ranging from 6–8 m (20–26 ft).
They usually grow in the mountains where precipitation from the incoming moisture off the ocean is greater. The tallest and oldest trees are found in deep valleys and gullies, where year-round streams can flow, and fog drip is regular. The terrain also made it harder for loggers to get to the trees and to get them out after felling. The trees ...
In Canada and Scandinavia, the growing season is often estimated by using the period of the year when the 24-hour average temperature is +5 °C (41 °F) or more. [16] For the Taiga Plains in Canada, growing season varies from 80 to 150 days, and in the Taiga Shield from 100 to 140 days. [17] Other sources define growing season by frost-free ...
Krummholz Pinus albicaulis in Wenatchee National Forest Wind-sculpted krummholz trees, Ona Beach, Oregon. Krummholz (German: krumm, "crooked, bent, twisted" and Holz, "wood") — also called knieholz ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds.
The world's tallest, thickest, largest, and oldest living trees are all conifers. The tallest is a coast redwood (Sequoia sempervirens), with a height of 115.55 metres (although one mountain ash, Eucalyptus regnans, allegedly grew to a height of 140 metres, [16] the tallest living angiosperms are significantly smaller at around 100 metres.
A stand of trees in excess of 10,500 years old was found in 1955 in western Tasmania on Mount Read. [106] 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. [107]

Aspen trees are all native to cold regions with cool summers, in the north of the northern hemisphere, extending south at high-altitude areas such as mountains or high plains. They are all medium-sized deciduous trees reaching 15–30 m (50–100 ft) tall. In North America, the aspen is referred to as quaking aspen or trembling aspen because ...
