Northern Japan is home to the Japanese tree lilac. Plants can be found growing on limestone cliffs and amid brush. The Japanese tree lilac is bigger and blooms later than the shrub lilacs. It blooms in huge clusters of tiny creamy-white flowers that are aromatic. Simple, opposite, whole, ovate leaves that are 3 to 6 inches long, half as broad, and have a long, tapering tip. The medium to dark green leaves have a fuzzy underside. In the autumn, the deciduous leaves develop a pale greenish-brown colour before falling.
