During the autumn months the dawn redwood, Metasequoia glyptostroboides, in the Walled Garden glows with a vivid brick-red colour, resembling a flaming torch. Known only in fossil records until the 1940s, the dawn redwood is often described as a ‘living fossil’. It is the only living member of the genus Metasequoia, although the fossil record shows us that it was distributed through North America and Eurasia up to 100 million years ago. Today, the dawn redwood is restricted to the border of two Chinese provinces and Chongqing in Central China, but it is a popular addition to many parks and gardens in Europe and America. Despite this, it is still internationally recognised as endangered.
