The Japanese Tree Lilac is a small, specimen tree or large shrub that has stiff spreading branches with a somewhat oval-rounded to vase shaped crown. This handsome landscape tree grows upright, to about 30 feet, and has a wide trunk. It produces very showy, cream-white flowers in large panicles in June and July. Clumps will have three or more stems.
This ornamental tree displays reddish-brown, cherry-like bark that is sometimes smooth and lustruous. The leaves are clean and dark green and enhance seasonal interest. Lawn fertilizer contains nitrogen, so avoid using it around the base of this Lilac tree. When pruning, it is important not to remove too much since this will reduce the flower output the following year. Prune immediately after flowering to avoid removing flower buds.
Regular watering will maintain a healthy and beautiful plant. This Tree Lilac prefers full sun and moist, well drained, slightly acid soil. Tree lilacs are dependable urban trees. They can be used for parking lot or boulevard plantings, which tolerate a wide range of conditions. Use as farm windbreaks or highway beautification too.
