The name "Dawn Redwood" for Metasequoia glyptostroboides originates from the fact that it was a "rediscovered" species, as it was thought to be extinct but was found alive in China in the 1940s. The name "Dawn" symbolizes the rebirth or "dawning" of this ancient species in modern times. The "Redwood" part of the name is a reference to the tree's resemblance to the giant sequoias and coast redwoods.
