The following trees from the past Seminars 62 - 70 have been written with information gathered from personal observations of the author, living in Massachusetts Zone 6, and information provided by J. Frank Schmidt & Son.
Dawn Redwood
Metasequoia glyptostroboides commonly known as Dawn Redwood was known only from paleo-botanical records or fossils dating back to the Mesozoic times. In 1945, a man known as T. Wang found this tree to exist in the form of single living species in northeastern Szechuan, near the Hupeh border in China. The live Metasequoia trees were found confined to 3 individual trees scattered along small streams. It is also extraordinary that only four years after the Metasequoia was actually described from the fossil records, that living species of the genus should be found in China. Even more extraordinary is that when found, this living species, the sole surviving representative of a former widely distributed genus, was apparently on the verge of extinction as a living entity in its native habitat.
Fortunately this tree has excellent germination and is now established in various parts of the United
States and other locations around the globe.
Botanical Name: Metasequoia glyptostroboides
Common Name: Dawn Redwood
Parentage: Prehistoric tree found in China and introduced in 1948 by Arnold Arboretum
