![]() The female seed cones normally appear terminal at the tip of the branches and are solitary, globose, oblong or ovoid and are dehiscent or indehiscent when mature in 1 st, 2 nd or 3 rd year. There are 6-16 microsporophylls that are decussate or whorled and normally have 3 - 6 pollen sacs that release wingless pollen. These plants may be monoecious or dioecious with the pollen male cones arranged terminally or axillary, normally solitary and shedding annually. They are arranged in alternately pairs (decussate) or in whorls of three. The leaves are simple, linear and needle-like particularly in the juvenile stage and commonly with an abaxial resin glands or are scale-like and keeled, adherent to the internode on the stem. Mainly found in the northern hemisphere with a concentration in North America, Europe and Russia appearing in a wide range of habitats from alpine to arid, from sea level to high altitudes. This family consists of evergreen shrubs and trees that are monoecious or dioecious and are normally columnar to conical shape with scale or needle-like leaves on 4 angled, terete or flattened branches. It prefers a well-drained moist fertile soil and grows in USDA zones 4 - 6. It has grey-green foliage that turns deep orange during autumn and grows in an open sunny to partially shaded protected position. This dwarf coniferous shrub grows to 2.5 m (8 ft) tall by 1 m (3 ft) wide over a 10 year period with an upright trunk and graceful weeping branches. The Greek prefix meta, "associated with", implies that this is not a true Sequoia "glyptostroboides", from Greek glypto, "carved", + strobus, "a fruit", + oides, "resembling" - thus, the cones look like wood carvings. Metasequoia (me-ta-se-KWOY-a) glyptostroboides (glip-to-stro-BOI-deez) It is not suitable for a small garden and care should be taken when selecting a site as the roots can cause damage. Once established it has a high water requirement (Scale: 3-drops from 3), preferring organic rich reliable moist deep soil during summer. It is also planted along borders as a summer screen and establishes in 4 to 7 years as a sapling then matures in 50-60 years and can live for up to 200 years or more. ![]() It is planted in parks and large gardens as a specimen tree or used as a focal point in a formal garden. It grows in a open sunny to semi shaded position and is frost and snow tolerant but drought tender.Äawn Redwood is grown for its foliage, its conical habit and its autumn colour. It prefers a well drained deep moist sandy to clay or loamy soil that is acidic to slightly alkaline with a pH range from 5.0 to 7.5 and will tolerate chalky soils. Since then it has been propagated worldwide. Metasequoia glyptostroboides was thought to be extinct until it was discovered in 1941 in eastern Szechwan and Hupeh provinces in China. It has graceful spreading branches that form a conical habit with small bright green linear leaves turn yellow-brown during autumn. Oregon State Univ.This deciduous conifer has a straight trunk with red bark that turns grey-black with age and comes away in stringy strips. The Story of the Discovery and Naming of Dawn RedwoodĬorvallis: tree in Riverfront Park, just south of the Harrison Ave.Metasequoia flourished in the Miocene epoch of 25 to 5 million years ago and left its record embedded in rocks across the Oregon landscape. State Fossil of Oregon: The Oregon legislature designated the Metasequoia as the official state fossil in 2005. 'Miss Grace' - more or less ground sprawling, but if staked, a small tree with weeping branches.'Gold Rush' - bright yellow foliage in spring and retains much of the color throughout the summer.Several cultivars are available, including: Hardy to USDA Zone 4 Native to Sichuan (Szechuan, Szechwan), China. Easy to transplant, performs best in moist, well-drained, slightly acid soils. Pollination occurs in early spring and the seeds in the female cones are mature by the fall. (However, because of western Oregon's wet, but mild, winters, the cones are not dry enough to open and release the seeds until the following spring.) The female (seed) cones are solitary, oval, green then light brown, about 2 cm long male (pollen) cones are arranged in long pendant clusters, each cone is globose and about 5 mm long. Bark reddish brown when young, darker, fissuring, and exfoliating in strips when mature. The trees are monoecious, both male and female cones on an individual plant. Needles are arranged in opposite pairs, each is about 15 mm long, straight or slightly curved, bright green above, light green below. Deciduous conifer, 70-100 ft (21-30 m), excurrent, pyramidal, flat topped when mature.
