Broadleaf Lilac Syringa oblata

Early lilac is a perennial shrub or tree in the olive family (Oleaceae). It is native to China. The species epithet, Latin for “oblate,” highlights the fact that the leaves are wider than they are long.

It is hardy, preferring hot summers and cold winters. Good air circulation is needed to prevent diseases. Early lilac grows best in moist, fertile, well-drained soils where the pH hovers between slightly acidic and slightly alkaline. Removing the spent blooms before they set seed will give you more blooms the next year.

This is the earliest-blooming lilac, but consequently, flower buds are susceptible to frost injury in early spring. This is the only lilac that gives any appreciable autumn color. 

This is best planted near a patio or walkway where the fragrance can be enjoyed.

Insects, Diseases and Other Plant Problems:  Powdery mildew can be an issue on the foliage in late summer.  Leaf spot may also appear.  Aphids, caterpillars, borers, and scale are insects that may damage this plant.
