The soil there is frozen from 25 to 90 cm (10 to 35 in) down, making it impossible for trees to grow there. Instead, bare and sometimes rocky land can only support certain kinds of Arctic vegetation, low-growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen.

The trees, planted in 1936 by the Forests Commission Victoria, were initially slow to establish but have thrived and grown to a height of over 60 metres (200 ft). Measurements in 2004 showed the trees have the potential to be as tall as their Californian counterparts, if left undisturbed from bushfire, pests and disease, or trampling by tourism ...
Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season. Some alpine plants serve as medicinal plants. Alpine meadows in the Kazbegi National Park, Georgia
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 ...
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]

That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with any potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, growing (biologists say, turning; see tropism ...
