Dawn Redwood (Glyptostroboides)

The greatest bloom is usually observed in the spring, with fruit and seed production starting in the summer and continuing until summer. Leaves are not retained year to year. The Dawn Redwood (Glyptostroboides) has a long life span relative to most other plant species and a rapid growth rate. At maturity, the typical Dawn Redwood (Glyptostroboides) will reach up to 100 feet high, with a maximum height at 20 years of 60 feet.

The Dawn Redwood (Glyptostroboides) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, cuttings, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -13°F. has low tolerance to drought and restricted water conditions.
