Metasequoia glyptostroboides (Dawn Redwood) is a tree that looks similar to the Redwoods that grow in the Redwood National Forest (Sequoia sempervirens, Coast Redwood) and the Sequoia National Forest (Sequoiadendron giganteum, Giant Sequoia). Metasequoia glyptostroboides has a much shorter mature height of 70 to 100 feet as opposed to the record Sequoia sempervirens of 379 feet!! The foliage has a soft fern like appearance with exfoliating bark and a pyramidal form making it a perfect specimen tree where adequate space is available. Metasequoia glyptostroboidesprefers likes moderately wet soil making it a good rain garden choice.
Dawn Redwood is also a fast growing tree. This past spring in the nursery, we planted ten Dawn Redwood trees into 15 gallon containers and were about less than 1” in caliper. At the end of the season, the Dawn Redwoods had an approximate caliper of 1.5” and a stunning 2 feet of new growth! While Metasequoia glyptostroboides is of the hardiest redwood/sequoia family, it still is a zone 5 making winter hardiness in Minnesota a potential problem. Our Dawn Redwoods are currently heeled in a cozy layer of mulch for the winter to keep the roots insulated (right image). Hopefully come next spring, all ten will have survived this cold winter and will be able to be planted out in the city!
By planting unique species like Dawn Redwood in Minnesota will help diversify the urban forest. The ten trees that we will plant out in the city will be a helpful trial on how well they perform in the harsh Minnesota winters. While Metasequoia glyptostroboides is a zone 5 tree, micro climates in the city should help the likelihood of survival when extreme cold hits.
