Japanese tree lilac, or Syringa reticulata, is a species of Lilac native to eastern Asia, northern Japan, northern China, Korea, and far southeastern Russia. It is a deciduous tree growing to a height of 25 feet, rarely much more. It is the largest species of lilac, and the only one that dependably makes a small tree rather than a shrub.

It has elliptical leaves with a rough texture, of a good medium green, and attractive bark similar to cherry trees. But, of course, being a lilac its greatest asset are the showy clusters of creamy white, musky-scented flowers in early summer, some up to a foot long.

One particular noteworthy cultivar is 'Ivory Silk'- In every regard, Ivory Silk Lilac is the same as the species Japanese tree lilac, except that it is more compact, smaller at maturity, to 20 feet instead of 25 and narrower profile. Additionally it has a stronger fragrance and flowers heavily and at a younger age.

This is the most problem-free lilac and is well-suited as a street tree, lawn specimen or informal screen. It will grow in full sun, in moist, well drained, slightly acid soil. Japanese tree lilacs prefer cooler regions. It grows well throughout the UK, the upper half of the US, and is an excellent choice for Canada. It also does well in temperate Australia and New Zealand.
