During three months in the summer, the sun would shine continuously, while three months of the winter would be complete darkness. Given that the high latitudes in this period were warm and tropical, it is hypothesized that the deciduous habit evolved in response to the unusual light availability patterns, not to major seasonal variations in temperature. Metasequoia was likely deciduous by this time. During the Paleocene and Eocene, extensive forests of Metasequoiao ccurred as far north as Strathcona Fiord on Ellesmere Island and sites on Axel Heilberg Island (northern Canada) at around 80 degrees North latitude. 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. Sequoioideae and several other genera have been transferred from the former Taxodiaceae family to Cupressaceae based on DNA analysis. 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. Local villagers refer to the original tree from which most others derive as Shui-sa, or "water fir", which is part of a local shrine. Although the least tall of the redwoods, it grows to at least 165 feet (50 meters) in height. It is native to Lichuan county in Hubei province, China. Metasequoia ( dawn redwood) is a fast-growing deciduous tree, and the sole living species, Metasequoia glyptostroboides, is one of three species of conifers known as redwoods. I am a treelover and part of the appeal of the park is the 175 species of trees that are taken good care of, some 20,000 in total. What a shame that was, and the local councilman who allowed that to happen out to be voted out. One may be found on Amsterdam Avenue and 73rd Street, and four were planted on Bennett Avenue and 191st Street, only to be hacked down by the city for some unknown reason. There are seven other redwoods in Central Park, found together in one spot near Fifth Avenue and 102nd Street. Sow chitted seeds and return balance to pretreatment until no more seeds germinate.This is a photo of one of the three Dawn Redwoods in Strawberry Fields, taken in Autumn of 2018. At suitable intervals, remove chitted seeds (by hand, flotation, and/or sieving).

(?) - indicates storage characteristics are not yet fully understood.Ī Maximum advisable storage c. Recalcitrant - seeds that cannot be dried or frozen and are therefore short-lived. Orthodox - seeds that can be dried without harm, and once dried can be frozen, stored for years with little deterioration and relatively easily revived.

They deteriorate more quickly than 'orthodox' seeds but more slowly then 'recalcitrant' seeds. Intermediate - seeds that can only be partially dried or need very slow, careful drying.
