Old trees of this species are said to be the largest living organisms on this planet, however, before you can stand under one of these massive, awe-inspiring giants of your own, unfortunately you would have to wait at least several hundred years. The good news is that Sequoiadendron is fast growing and even the young trees are very attractive, with a highly symmetrical, conical crown, and perhaps much better suited to gardens with limited space available. The giant sequoia is native to the western slopes of the Sierra Nevada in central California, between 900 and 2700 m (3000 and 8900 ft.), where sizable groves of it are found in a mixed coniferous forest with several other giant species. The oldest living trees have an age of just under 3000 years, a height of nearly 95 m (300 ft.) and a base diameter of 10 m (33 ft.). It is easy to grow from seed, which needs cold stratification for about a month, and suited to most temperate climates from USDA zones 6 to 8. The wood is highly rot-resistant and Sequoiadendron has potential as a commercial timber tree but is not frequently planted for this purpose. It is a very popular ornamental tree however.
