1/8/2024 0 Comments Metasequoia north lightMetasequoia was likely deciduous by this time. During the Paleocene and Eocene, extensive forests of Metasequoia occurred as far north as Strathcona Fiord on Ellesmere Island and sites on Axel Heiberg Island (northern Canada) at around 80° N latitude. Fossils are known from the Cenomanian onwards. Metasequoia redwood fossils are known from many areas in the Northern Hemisphere more than 20 fossil species have been named (some were even identified as the genus Sequoia), but are considered as just three species, M. foxii, M. milleri, and M. occidentalis. 4 Metasequoia in gardens, parks and streets.Sequoioideae and several other genera have been transferred from the former family Taxodiaceae to Cupressaceae based on DNA analysis. M. glyptostroboides is the only living species in its genus, but three fossil species are known. Together with Sequoia sempervirens (coast redwood) and Sequoiadendron giganteum (giant sequoia) of California, Metasequoia is classified in the Cupressaceae subfamily Sequoioideae. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental, with examples found in various parks in a variety of countries. Local villagers refer to the original tree from which most others derive as Shuǐshān (水杉), or "water fir", which is part of a local shrine. Although the shortest of the redwoods, it grows to at least 165 feet (50 meters) in height. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. *Information from Michael A.Metasequoia, or dawn redwoods, is a genus of fast-growing deciduous trees, one of three species of conifers known as redwoods. Native Range: eastern Szechuan and western Hupeh China Lower slightly lighter in color, raised midribīark: reddish brown when young>darker, fissured, and exfoliating with ageĬulture: moist, deep, well-drained soil full sun little to no pruning appears to tolerate very wet sites Leaves: opposite, deciduous, flattened, straight or slightly curved, 1/2", upper bright green, Metasequoia glyptostroboides Bibliography and Other Resources-coming soonįlower: monoecious male flowers are racemes or panicles up to a foot long, female flowers are solitaryįruit: pendulous cones, globose or cylindrical, 3/4 to 1 1/4", 14-28 scales, mature in 5-7 monthsīuds: 1/4" ovoid or ellipsoid, bud scales light reddish or yellowish brown, opposite They are fast-growing, so even though our specimen is small, we might live to see it reach impressive height. It's exciting to have one planted in Maxwell and I hope it does well. Before dropping its leaves, it can have incredible fall color, especially when lit up on a sunny day.

And don't miss Doug Hank's wonderfully obsessive site about his planting project in North Carolina. Check out the web site for the latest info including annual conference information. A quick overview on Wikipedia can get you started and the compilation of historic and contemporary articles published as "Metasequoia After Fifty Years" by the Arnold Arboretum's Arnoldia in 1998-1999 will give you the best history available. The story of the discovery of a handful of remnant trees in Hubei Province and subsequent explorations is one of the most fascinating tales in modern botany. The literature concerning Metasequoia glyptostroboides is vast and well worth exploring. With the reopening of China to botanists in the late 1970s, new seed sources were available to bring in fresh genetic material. The oldest Metasequoia in the country were all propagated from these seeds. In 1946, the Arnold Arboretum obtained seeds from China and distributed them throughout the country. Its rediscovery in a remote mountainous region of China in the early 1940s rocked the botanical world.
