Sequoiadendron giganteum or “Talking Leaf”

24 September 2014. Towering above every other tree on earth, save for the Coast Redwood (Sequoia sempervirens), this coniferous Giant Sequoia (Sequoiadendron giganteum) is the largest tree by volume and lives in the federally-protected groves of Sequoia National Park in the Sierra Nevada mountains of Central California.  Belonging to the Cupressaceae family and Sequoioideae subfamily it’s one of the three redwoods along with the Coast and Dawn (Metasequoia glyptostroboides) redwoods.


The tree is purportedly named after Ssiquoya, the silversmith and inventor of the Cherokee syllabary (pictured inset, created around 1809).
