A collection of 3 Redwood Trees - 1 plant each of; Metasequoia glyptostroboides, Sequoiadendron giganteum, and Sequoia sempervirens supplied in 9cm Pots.
The name sequoia sometimes refers to the subfamily Sequoioideae, which includes S. sempervirens along with Sequoiadendron (Giant Sequoia) and Metasequoia (Dawn Redwood). Referred to generally as ‘Redwoods’.
Metasequoia glyptostroboides makes a fine tree now familiar due to its remarkable appearance. The beautiful ferny foliage is a bright emerald green in spring, turning russet-brown with tints of coppery pink in autumn. The strong pyramidal winter silhouette is also very attractive and older trees form wide buttresses on the lower trunk and form a distinctive "armpit" under each branch. The bark is vertically fissured and tends to exfoliate in ribbon-like strips., making the Dawn Redwood a strong contender for year-round interest. It prefers a damp habitat, and is best planted near to water if the land is typically well drained, but also makes a perfect Bonsai specimen for the windowsill. Metasequoia glyptostroboides, otherwise known as the Dawn Redwood, is a fast-growing, endangered and coniferous tree - the sole living relic species of the genus Metasequoia, one of three species in the subfamily Sequoioideae. It is native to Lichuan County in the Hubei province of China. Although shortest of the redwoods, it can still grow to at least 200ft (61m) in height. From fossil records this tree was common across the northern hemisphere and the Dawn Redwood was originally considered extinct. The genus Metasequoia was first described in 1941 as a fossil of the Mesozoic Era, and none of the fossils discovered were less than 1.5 million years old. Dr. Shigeru Miki (1901–1974), a paleobotanist from Kyoto University, identified a divergent leaf form while studying fossil samples of the family Cupressaceae and realized he was looking at a new genus, which he named Metasequoia, meaning"like a sequoia."
Sequoia sempervirens is the sole living species of the genus Sequoia in the cypress family Cupressaceae. Common names include Coast Redwood and California Redwood. It is an evergreen, long-lived, living 1,200–1,800 years or more. This species includes the tallest living trees on Earth, reaching up to 379 feet (115.5m) in height (without the roots) and up to 29.2 feet (8.9m) in diameter at breast height . These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500km2) along much of coastal California and the southwestern corner of coastal Oregon. There is some evidence that the species is the result of a pre-historic hybridisation between Sequoiadendron and Metasequoia or ancestors of them, when the two species were not so distantly separated. This seems plausible as although the foliage of Sequoiadendron in dissimilar to the other Redwoods, it is evergreen which the Dawn Redwood is not – Sequoia sempervirens being in effect an evergreen Dawn Redwood.
Sequoiadendron giganteum Giant Sequoia; also known as Giant Redwood and Wellingtonia are the world's largest single trees and largest living thing by volume. Giant sequoias grow to an average height of 50–85m (164–279ft) and 6–8m (20–26ft) in diameter. Record trees have been measured to be94.8m (311ft) in height. Claims of 17m (56ft) diameter have been touted by taking an author's writing out of context, but the widest known at chest height is closer to 8.2m (27ft). Between 2014 and 2016, specimens of Coast Redwood were found to have larger trunk diameters than all known Giant Sequoias. The oldest known Giant Sequoia based on ring count is 3,500 years old. Giant Sequoias are among the oldest living things on Earth. The natural distribution of giant sequoias is now restricted to a limited area of the western Sierra Nevada, California.For most of us these trees are far too big for garden planting, but make interesting pot plants or bonsai specimens.
