Did you know
- Japanese zelkova is the most widely planted elm-family tree in North American cities, replacing American elms lost to disease.
- Its flowers are tiny and wind-pollinated — clustered at leaf axils and essentially invisible to the casual observer.
- The graceful vase shape develops naturally without pruning, making it an ideal low-maintenance street tree.
- In Japan, massive zelkova beams were used for castle construction because the wood resists rot and insect damage.
- The village of Higashishirakawa in Gifu Prefecture protects a zelkova estimated at 1,100 years old.
