Wang collected several branches and hoped to also gather cones, but these were too high in the tree. Wang and his crew changed their travel plans and went to Modaoxi to see the tree, arriving July 20, 1943. Metasequoia living fossil вЂ“ image by deelish.ieДЄ couple years later, Zhan Wang of the National Bureau of Forest Research in China was leading an expedition to collect modern plants in south-central China when he learned of an unusual large tree growing in Modaoxi. Many of the fossils previously described as Taxodium and Sequoia were thus attributed to this new genus. In 1941, Japanese paleobotanist Shigeru Miki was studying samples of Taxodium and the related redwood Sequoia when he realized that many of the specimens had enough unique characteristics to qualify as a new genus, which he named Metasequoia. Abundant fossil were recovered in Oregon in deposits as young as 5 million years old. Geologist John Strong Newberry вЂ“ image by ДЄs the years passed, other collectors found countless samples of this taxon, from Alaska, Canada and the northern United States. He concluded the specimens all belonged to a previously unknown species of cypress-like conifer that he named Taxodium occidentale. Years later, in 1863, geologist John Strong Newberry compared this picture to fossils collected along the Washington coast by geologist George Gibbs as part of the U.S. In his scientific description of the expedition, Geologist James Dwight Dana figured a fossil plant that had been collected in or near the area encompassed by modern-day Washington state. In the middle 19th century the United States Congress authorized an exploring and surveying expedition to the Pacific Ocean that ended up running from 1838 to 1842. If youвЂ™d like to see a Dawn Redwood in person, you can find one here at Reiman Gardens just south of the Home Production Garden.The conifer Metasequoia, which lived in Oregon as late as 5 million years ago, was declared the stateвЂ™s fossil in 2005. With enough space, however, the Dawn Redwood can be an attractive and impressive addition to the landscape. For this reason, they may grow too large for smaller gardens. As one would expect, Metasequoia grows very quickly individuals planted in the 1940s have already exceeded 80 feet in height. Much like Bald Cypress, the Dawn Redwood requires adequate water availability, and will thrive in areas with standing water.

It is a vigorous grower, hardy to USDA Zone 5, and prefers full sun. Though the Dawn Redwood is considered endangered in its natural range, it has become a popular ornamental tree in parks and gardens worldwide. In the wild, trees have been found to be more than 150 feet tall. Although it is the shortest of the redwoods, the Dawn Redwood can easily reach 70 to 100 feet in height. New growth is light green, maturing to a deep green in the summer, and eventually turning red-bronze and falling off in autumn. The Dawn Redwood features feathery, fern-like foliage that is soft to the touch. While the bark and foliage of the Dawn Redwood are similar to the other redwoods, it is distinct in that it is deciduous and develops a widened trunk-base as it matures, not unlike the Bald Cypress ( Taxodium distichum). In fact, these three species completely comprise the Cupressaceae subfamily Sequoioideae, or the redwood subfamily. It is the sole living member of the genus Metasequoia, which literally means вЂњalmost a sequoia.вЂќ As this name implies, the Dawn Redwood is closely related to the Coast Redwood ( Sequoia sempervirens) and the Giant Sequoia ( Sequoiadendron giganteum). The seedlings grown from this seed were then distributed to universities and arboreta around the world in an attempt to preserve the species.ДЇrom fossil data, the Dawn Redwood is known to have existed as many as 50 million years ago. After discovering that the Dawn Redwood was in fact not extinct, the Arnold Arboretum of Harvard University sent an expedition to collect seeds from the discovery site. This hypothesis was proven false only 6 years later in 1947, when a small stand of unidentified trees in Southwest China was found to belong to the already described fossil species. At that time, it was believed to have been extinct for millions of years. This conifer was first described in 1941 based only on fossil evidence. The living fossil in reference is the Dawn Redwood, Metasequoia glyptostroboides.
