flowers of a Japanese lilac tree are similar to those on a
lilac bush, but generally have smaller individual blossoms.
The range of color is also more limited, usually only cream
to pink, but some purple cultivars have been introduced. The
blooms generally appear after those of lilac bushes, and will
last about the same length of time. Therefore, planting a
Japanese lilac tree behind a row of lilac bushes will allow
for the lilac blooming season to be extended by a few weeks.
lilac tree should be protected from damage caused by wind
and other natural sources, as well as human damage. This is
because Japanese lilac trees take a fairly long time to recover
from damage. When damaged enough, Japanese lilac trees may
not bloom for a few years, as they are focusing their energy
on repairing the damage instead of making new buds. The wood
of Japanese lilac trees is softer than that of some of the
larger trees, and can therefore be damaged more easily. Japanese
lilac trees have fragrant blooms, and will provide a good
amount of shade.
Japanese lilac tree 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 Japanese lilac tree,
as this will likely reduce the flower output the following
year, in much the same way that damaging the tree with wind
will. When cared for properly and given the proper growing
conditions, a Japanese lilac tree can easily survive for nearly
one hundred years.
