Giant sequoia, also called big tree or wellingtonia, is the largest tree on Earth by volume, native to the western Sierra Nevada of California. These massive evergreen conifers reach 250+ feet tall with massive, unbranched trunks and fibrous, reddish bark up to 2 feet thick. The foliage is blue-green and scale-like.
Giant sequoia naturally grows in deep, well-drained soil in groves where fire historically promoted regeneration. The trees are extremely long-lived (over 3000 years) and grow moderately fast once established. Outside their native Sierra Nevada habitat, they require cool climate with adequate moisture and are rarely grown except in botanical collections.
