Description
Sequoia sempervirens is the tallest living tree species on Earth, featuring thick, fibrous, reddish-brown bark that is deeply furrowed. The foliage consists of flat, needle-like leaves that create graceful, fern-like sprays. As a conifer, it produces small, woody seed cones and drops older branchlets seasonally rather than individual needles.
Habitat
Coastal temperate rainforests characterized by heavy winter rains and frequent summer fog, which provides crucial moisture during dry periods. Thrives in deep, moist, alluvial soils along streams and valley bottoms.
Native Range
Native to a narrow strip of coastal fog belt in western North America, primarily stretching from the central coast of California up to southwestern Oregon. Widely planted as an ornamental in suitable temperate climates globally.
