At maturity, the typical Japanese Zelkova (Serrata) will reach up to 89 feet high, with a maximum height at 20 years of 40 feet.

The Japanese Zelkova (Serrata) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, 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 -33°F. has none tolerance to drought and restricted water conditions.
