Syringa vulgaris, or common lilac, are considered invasive in Ontario and most of Canada due to prolific suckering and are not recommended to plant. The native range includes rocky hills and open woodlands in southeastern Europe. It prefers rich, moist, neutral to calcareous soil with good drainage. It is known for its sweet fragrance, and is found commonly in hedges in urban areas. For better airflow to prevent mildew, it's recommended to prune the center of the plant and to prune immediately after flowering. Some suitable alternatives are the Amelanchier and the Halesia carolina.
