Face view of cone scale looks like puckered lips.Female cones are pendulous and ellipsoidal.Pins are opposite and resemble small pinnate leaves.It was first known from a fossil record, not living extant plants. Dawn Redwood was discovered during a plant expedition into remote China in the 1940s. It needs plenty of room to grow as it can grow to be 25' wide. It is also tolerant of pollution and can be used as a street tree. It can be utilized as a specimen tree for large areas such as parks, golf courses, large commercial or governmental grounds, and as a 'living fossil'. This plant has minimal pest and disease problems. It is tolerant of wet soils but intolerant of early freezes. This plant prefers moist, deep, well-drained soils that are slightly acidic. Pin branchlets are paired, and drop as a unit. It has spreading branches that droop with age. This is a large, fast-growing, deciduous, pyramidal evergreen tree that grows up to 100' tall with attractive, feathery foliage that is easy to transplant. This is not an exhaustive list.Phonetic Spelling met-uh-see-KWOY-uh glip-toh-stroh-BOY-deez Description Cuttings can also be rooted to perpetuate desirable traits.Ĭultivars of some note which are available in commerce are listed below. Seedlings will grow 6’ high in a 3-gallon container in a single season (zone 8). I have collected cones as they open, harvested seeds, stratified for 30 days, with excellent germination. The cones are similar to Sequoia sempervirens, ovoid, egg-shaped, ¾ to 11/4” long, with 14 to 28 scales, maturing in autumn and opening to shed the small, light brown, winged seeds. New, smaller statured cultivars are available which counters the size argument. However, this is a great asset for parks, campuses, golf courses, and commercial grounds. If there is an Achilles heel to use in contemporary landscapes, it would center on size. I noted branch dieback on a tree at the University of Maine, Orono (zone 4). Hardness is listed at zone 5 to 8, which is reasonably accurate. distichum, develops chlorosis on high ph soils. I have not observed chlorosis on the species whereas, T. Trees are wind-firm and resistant to breakage. Growth is fast, easily 2 to 3’ per year, for the first 10 years, if provided reasonable care. The species is surprisingly well suited to drier soils once established. Netherlands, I observed an entire street planted with Metasequoia. Extremely tolerant of excess moisture and I observed trees in standing water. Excellent tree along streams and in moist soil areas. Single specimens, grouping and groves inspire. Tree bark glows rich saturated orange-red in the late afternoon winter sun. Though deciduous, the unique branching and bark characteristics provide exquisite winter beauty. The bark is beautiful, rich reddish brown, slightly shedding in thin strips, the trunk with cavities under each branch attachment. The opposite arrangement permits easy separation from Taxodium distichum, common baldcypress, with alternate branches and buds. The needle-bearing branches, oppositely arranged, abscise in toto in fall. Habit is soft, feathery, conical pyramidal, the needles bright green, turning rusty orange to brown in autumn. Considering the narrow gene base (diversity), many unique cultivars have resulted from the original introduction (see cultivars) This is a large tree, easily 70’ by 30’ at maturity. Louis, houses many of the original seedlings and introduced Shaw’s Legacy™ (‘Peter Raven’, notable because of the denser conical pyramidal habit and darker green needles. Seeds and seedlings were distributed to many public gardens and universities with trees now over 100’. The species, Metasequoia glyptostroboides, was considered extinct until rediscovered in the 1940s in China and reintroduced via the efforts of the Arnold Arboretum, Jamaica Plain, Massachusetts.
