Syringa oblata,  commonly known as Broadleaf Lilac and Early Blooming Lilac, is native to China and Korea. In its native habitat it grows in thickets and woodland margins.

Syringa is derived from the Greek syrinx meaning ‘a tube’, possibly alluding to its hollow stems. Oblata is derived from the Latin oblatus menaing ‘somewhat flattened at the ends’.

The landscape architect may find Syringa oblata useful as a free flowering shrub with an attractive scent. It is a suitable shrub for using to create a deciduous hedge.

Ecologically, Syringa oblata flowers are attractive to pollinating insects including bees.

Syringa oblata prefers moist, humus rich, well-drained soils. It tolerates most pH of soil, although it prefers slightly acidic soil.

Syringa oblata requires little maintenance. Flowers may be removed after they have faded and before they set seed to increase flowering the following year. Any necessary pruning should be carried out after flowering. Syringa oblata flower on old wood and will produce more flowers if left unpruned. Over mature specimens may be rejuvenated by pruning the plant hard to encourage vigorous new growth.
