The Coastal redwood is the tallest tree on earth. The highest individual at this moment is the ‘Hyperion’, reaching up to 115,5 meters high and almost 9 m wide. According to research, the maximum height of a tree can be 120-130 under ideal conditions. Because the climate in Europe is less favorable, the trees will not reach this height. The highest individual in the Netherlands grows in Arboretum Trompenburg in Rotterdam, and measured 27,5 meters in 2006.
Sowing description: In general the seeds don’t germinate easily, but it’s definitely worth to give it a try. For the best result, it’s best to put the seeds away for 8 weeks in the fridge, after which they can be sown in sowing mix. Cover the seeds lightly with soil or sand, and let the seeds germinate at room temperature. Make sure the soil is constantly moist and put it in a bright stand without direct sunlight.
