how big does a Japanese lilac tree grow?
The habit is graceful, with spreading branches that form an oval to rounded crown. Plants can be grown as large shrubs or small trees. Japanese tree lilac grows 20 to 30 feet tall with a spread of 15 to 25 feet. Leaves are simple, opposite, entire, ovate, and 3 to 6 inches long, half as wide, with long, tapered tip.
If the tree is over-fertilized, or unhealthy in some way, flowering may be inhibited. It could be that the tree is being pruned at the wrong time, which would remove flower buds. Japanese Tree Lilac is one of the easier flowering trees to grow, and it may just be that it is not old enough yet to flower every year.
