[2] Fossils are known from the Cenomanian onwards. The discovery was confirmed in 1946 after the end of the Second World War. Mr. Cheng determined that the tree did not belong to Glyptostrobus pensilis, but was a new species. They sometimes grow too large in smaller gardens under favorable conditions, but they can be a good choice for a wide range of larger gardens and parks. The dawn redwood tree was long thought to be extinct until it was rediscovered in 1941 by Mr. T. Kan while performing a survey in the Hubei and Sichuan provinces of China. The discovery of "living fossil" instantly attracted attention from botanist around the world.

Although they live in wet sites in their native habitat they will also tolerate dry soils. Dawn redwood grows quickly into a large tree with a pyramidal shape and base that forms a wide flare. Not ornamentally important. USDA zones: 5-10. Hu recognized the living specimen was of the same genus of Miki's fossil genus ''Metasequoia''. Its needles are opposite on the stems (an easy way to identify it). Common names - dawn redwood, water fir, water larch Size Height - 70-100 ft Girth - Up to 100-120 cm Canopy spread - 25 ft Fast growing, grows late in season, with height increases of more than 24" per year when young and established. Fruit, cone, nut, and seed descriptions. Required fields are marked *. In 1941, Miki published the description of the fossil plant which he gave the name "Metasequoia". It is the sole species of its genre. Normal pH is a neutral of 7. Quick Jumps. To give you an idea of just how acidic this is, vinegar is 4, lemon juice is 3, and battery acid is 1. It is also hypothesized that the change from evergreen to deciduous trait occurred before colonizing the high latitudes and was the reason Metasequoia was dominant in the north.[5]. Deciduous conifer. Origin: Garden. Your email address will not be published. Redbud - 'Hearts of Gold' 249.99. The feathery, fine-textured needles are opposite and approximately 1/2 inch long. Before its discovery, the taxon was believed to have become extinct during the Miocene; when it was discovered extant, it was heralded as a "living fossil". It grows best in large landscapes. The bark becomes deeply fissured as the tree matures. Presently, a number of natural Metasequoia populations exist in the hills and wetlands of Hubei's Lichuan County. All rights reserved. Mr. Wang believed this tree belonged to an known species Glyptostrobus pensilis (水松) and filed the specimens away. The Dawn Redwood is a hardy tree growing in such diverse climates as Maine, Alabama, and California. Metasequoia glyptostroboides - Dawn Redwood. The discovery was confirmed in 1946 after the end of the Second World War. Common names - dawn redwood, water fir, water larch Size Height - 70-100 ft Girth - Up to 100-120 cm Canopy spread - 25 ft Fast growing, grows late in season, with height increases of more than 24" per year when young and established. © 2020 (Coniferous Forest). Needles (Leaves): 1 in (25 mm), feather-like arrangement, bright green, flattened, Flowers: Males are a light yellowish-brown arranged in clusters, while females are yellow-green and solitary, Cones: Globular to oval in shape, 0.59-0.98 in (15-25 mm) in diameter light brown, Soil: Tolerates a variety of soil conditions, including moist, well-drained, loamy, sandy, clay, and acidic. Sequoioideae and several other genera have been transferred from the former family Taxodiaceae to Cupressaceae based on DNA analysis. A large, conical-shaped tree reaching 70 to 100 feet high, dawn redwood is closely related to bald cypress (Taxodium) and redwood (Sequoia). The cones are globose to ovoid, 0.6-1.0 inches (1.5-2.5 cm) in diameter with 16–28 scales, arranged in opposite pairs in four rows, each pair at right angles to the adjacent pair; they mature in about 8–9 months after pollination. Serviceberry - 'Autumn Brilliance' 179.99. Given that the high latitudes in this period were warm and tropical, it is hypothesized that the deciduous trait evolved in response to the unusual light availability patterns, not to major seasonal variations in temperature. Reproduction in whole or in part without permission is prohibited. From NPS "The Giant Sequoia of the Sierra Nevada" updated 2007 : Dawn Redwood (Metasequoia glyptostroboides) Coast Redwood (Sequoia sempervirens) Giant Sequoia (Sequoiadendron giganteum) Size: Height-to 140 ft: to about 370 ft: to about 310 ft : Diameter-to 6 ft: to 16 ft: to 35 ft: … The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. In the bald cypress, they are seen to be in an alternate arrangement, meaning if there is a leaf-shoot on one side of the stem there will not be any on the opposite side, and instead will be a little above or below. The average seed germinates is 5 days. Together with Sequoia sempervirens (coast redwood) and Sequoiadendron giganteum (giant sequoia) of California, Metasequoia is classified in the Cupressaceae subfamily Sequoioideae. Local villagers refer to the original tree from which most others derive as Shui-shan (水杉), or "water fir", which is part of a local shrine. Crabapple - 'Coralburst' 149.99. Comparison of Dawn Redwood, Coast Redwood, and Giant Sequoia. In 1942, another botanist, Mr. Zhan Wang (王战)visited Modaoxi and collected living specimens. The cones are green at first, maturing to brown. Article was last reviewed on 26th December 2019. Height: 70-100’ Spread: 15-25’ Sun: Full sun. Add To Cart. Published on June 13th 2018 by Sudipto Chakrabarti under Cypress. Life expectancy Can live up to 600 years In urban areas it usually lives up to 60 years. Figure 4 - Photo from Missouri Botanical gardens - fall color. Cones are rounded and hang on stalks up to 1 1/2 inches long. Hardiness: Sunset zones: A3; 3-10. The pollen cones are 0.25 inch (6 mm) long, produced on long spikes in early spring; they are only produced on trees growing in regions with hot summers. Hydrangea, PeeGee. Although the potted redwoods require more attention, the larger redwoods often present more trouble when it comes to pruning, because of their size. Local villagers refer to the original tree from which most others derive as Shui-shan (水杉), or "water fir", which is part of a local shrine.
