Metasequoia - Dwan redwood
For a long time, Metasequoia, the primeval sequoia, was only known to us in Europe through fossil remains from the Cretaceous period. At that time, its range extended from Northern America via Greenland to the mixed forests of Northern Europe. With the Ice Age, the conifers were wiped out except for a small population in an inaccessible mountain region of China. It was not until 1941 that botanists discovered this Metasequoia population and since the 1950s descendants of this population have been reintroduced into Europe.
