Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8 ft) tall in 2019. [ 1 ] [ 3 ] Hyperion was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor . [ 4 ]
Common names include coast redwood, coastal redwood and California redwood. It is an evergreen , long-lived, monoecious tree living 1,200–2,200 years or more. [ 4 ] This species includes the tallest living trees on Earth, reaching up to 115.9 m (380.1 ft) in height (without the roots ) and up to 8.9 m (29 ft) in diameter at breast height .
Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a tree stops growing.
The tree has continued to grow and measured 113.11 m (371.1 ft) in 2010 and 113.61 m (372.7 ft) in 2013. [4] It is a specimen of the species Sequoia sempervirens , the Coast Redwood. The tree features three prominent burls on the southwestern side of its trunk and is surrounded by a large number of trees of almost equal size.

Fairly solid evidence indicates that coast redwoods were the world's largest trees before logging, with numerous historical specimens reportedly over 400 ft (122 m). [14] Hyperion, another coast redwood (Sequoia sempervirens), currently the tallest, is 115.85 m (380.1 ft), which also makes it the world's tallest known living tree. [15]
