Syringa × persica

Syringa × persica, the Persian lilac, is a hybrid, thought to originate from a cross of  Syringa × laciniata and S. afghanica. More compact than common lilacs, it grows up to 4 – and spreads about 5 –. Persian lilac prefers warmer winter climates (hardiness zones 5–9) than many species of lilac. Its hybrid with Syringa vulgaris, the common lilac, is Syringa ×chinensis, sometimes called Rouen lilac.

This is a different plant than Melia azedarach, also sometimes called Persian lilac.
