The world’s tallest tree is something that’s been a source of great debate, but it can’t be denied that the Sequoia sempervirens, or California redwood, is a source of great height. In 2006, one such tree, christened the Hyperion Redwood, was discovered deep in Humboldt Redwoods State Park. It measures 379.1 feet, or 9 feet taller than the previous tallest tree. Presumably, the Hyperion is still growing, as redwoods can live to be more than 2,000 years old. That’s old, but it has a long way to go to catch up with the world’s oldest living tree.
