Plant guide
Sweet mock orange
Philadelphus coronarius
Sweet mock orange is considered non-toxic to cats. Fragrant white flowers suit a garden border. “Mock orange” is shared with other plants, so confirm the botanical name.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: Philadelphus coronarius only. Confirm the botanical label; a photograph cannot identify a visitor’s specimen.
