Syringa × laciniata Syringa × laciniata Syringa × laciniata, the cut-leaf lilac or cutleaf lilac, is a hybrid lilac of unknown, though old origin. It is thought to be a hybrid between "Syringa vulgaris" from southeastern Europe and "Syringa protolaciniata" from western China.

It is a deciduous shrub growing to 2 m tall. The leaves are 2–4 cm long, variably entire
