The largest living tree species is the Giant Sequoia, known scientifically as Sequoiadendron giganteum. These majestic trees are native to the Sierra Nevada mountains in California and can reach impressive heights, often growing over 300 feet tall (about 90 meters). They are renowned for their massive trunk diameters and longevity, with some individuals living for over 3,000 years. Giant Sequoias thrive in specific environmental conditions, particularly in regions with ample rainfall and well-drained soil. Their immense size and towering presence make them a popular attraction in national parks, where they symbolize natural grandeur and resilience.
