smell the lilac trees

Lilac trees are very similar to lilac bushes, except that they grow more upright and have a wider trunk. Lilac trees can grow to a height of thirty feet, and usually have a rounded, upright shape. The most common of the lilac trees is the Japanese lilac tree. The Japanese lilac tree is hardy to zones three through seven. The heart shaped leaves of this lilac tree are dark green and deciduous.
The flowers of lilac trees are similar to those on lilac bushes, but generally have smaller individual blossoms.
Lilac trees should be protected from damage caused by wind and other natural sources, as well as human damage. This is because lilac trees take a fairly long time to recover from damage. Their wood is softer than that of some of the larger trees, and can therefore be damaged more easily. They have fragrant blooms, and will provide a good amount of shade.

They should be planted in a location of full sunlight, just like all other lilacs. When pruning, it is important not to remove too much from a lilac tree, as this will likely reduce the flower output the following year. When cared for properly and given the proper growing conditions, they can easily survive for nearly one hundred years.
