The tallest trees in the world are coast redwoods (Sequoia sempervirens). They are evergreen trees, growing up to 300 feet (91 meters)! Coast redwoods, often called California redwoods, can be found in coastal California and coastal Oregon. These trees need humidity, so most of them grow the mountains where moisture level is always sufficient. The tree named Hyperion, 379.7 feet tall, is the tallest of the coastal redwoods and all living trees ever discovered. It was found in 2006.
