Common lilac
Syringa vulgaris
Common lilac is considered non-toxic to cats. Its spring flowers can be enjoyed in a cat-conscious garden, with blooms and fallen cuttings kept away from nibblers.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: Syringa vulgaris only. Check the botanical name; a photo cannot establish the identity of your plant.
