England has no native redwoods. The two species—Sequoia sempervirens (coast redwood) and Sequoiadendron giganteum (giant sequoia)—are endemic to California and Oregon.
However, introduced specimens thrive in parks and estates:
Climate limits: UK lacks the coastal fog (redwoods) or Sierra Nevada snowmelt (sequoias) that drive maximal growth. But they survive, sequester carbon, and inspire.
For true redwood forests, book a flight to California. For a taste of their majesty, visit a British arboretum.
