They can, and they are - we planted one in the backyard when we came back from our first family trip to the USA in 1979. It is now some 30 meters high and dominates the area, the iron fence needed to be moved so the trunk (which is about 1.50m in diameter at chest height) fits, it is encroaching a bit on the cycle path behind the house. This is in Abcoude in the Netherlands, a village just below Amsterdam. There are several specimens of Sequoiadendron Giganteum [1] in the Netherlands, among them one [2] in the arboretum at Wageningen University (where I studied forestry). It is a hardy species which does quite well in the wet Dutch climate.

Awesome and mind boggling. 30 meters high in 42 years, that's some really fast growth, are you sure about the height? It sounds incredible already.

  It is somewhere between 25 and 30 m, I don´t know the exact height. The same goes for the diameter, this is a guesstimate. Having measured many trees it won't be that far off the mark though.

    “ The giant sequoia is the fastest growing conifer on earth given the right conditions. We expect 4 feet of upward growth in the third year for trees in large pots and one-inch plus growth rings. They have the potential to grow faster every year. Giant sequoias grow rapidly tall and less dense when the rising and setting sun is blocked. They quit growing tall rapidly once they reach full sun. Once they reach full sun they begin to grow a thick trunk, dense foliage, and rapidly put on weight.” https://www.giant-sequoia.com/faqs/giant-sequoia-landscape-questions/ https://www.giant-sequoia.com/faqs/giant-sequoia-landscape-q...
