The tallest tree in the U.S. is the coast redwood (Sequoiadendron giganteum), specifically a specimen known as Hyperion, which measures about 379.7 feet (115.7 meters) tall. Coast redwoods thrive in the moist, temperate climate of California's coastal regions, where they can grow for over 2,000 years. Their impressive height is attributed to favorable growing conditions, including rich soil, ample rainfall, and a foggy environment that reduces water loss.
