![]() Since 2000 it has reproduced numerous progeny throughout the neighboring forest. But it was not phased at all, and has healed over since and never slowed its growth. The big DR that I am standing beside the trunk, was struck by lightning around ten years ago, leaving a scar almost to the ground. I posted some pics of some of my favorite local middle TN DR's. If you push for extreme buttress and distorted base with dominant low limbs, then height growth may be less than I stated in my table. Then commensurately lowering for future years. My 50 years of records and studies reveal that in TN, on an average to good site, you should expect these growth rates : Likes moist well drained soil just like most trees. If growing an individual specimen tree, never trim branches above thigh high. Give full sun and perimeter room to grow. I have five here at my estate Arboretum (Two are the Goldrush / Ogon types. My biggest DR now approaches 90 feet high and 3 feet dbh. Since then I have studied and planted many in Tennessee. Even in 1967 this tree was over 60' even though it hadn't been brought to USA but a couple decades. Seeds given to Vanderbilt University in Nashville, one of which was planted near my home, in the late 1940’s. In 1967 I regularly watched and studied one of the first Dawn Redwoods planted in the U S A. Studying and growing the species since 1967.

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.
