Plant identification

Optimum conditions for growth
Lilacs grow best where there is a pronounced winter chilling. Some varieties will bloom with only little chilling. In inland valleys, they do best with light shade and protection from reflected heat. In other areas, plant in full sun. All lilacs prefer alkaline soils and good drainage. Provide water during bloom and heavy growth periods.
