Hollyhock
Alcea rosea
Hollyhock is non-toxic to cats. Its tall flower spikes can add color to a cat-conscious garden; keep cats from eating the flowers or leaves.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: Alcea rosea only. Check the botanical name; a photo cannot establish the identity of your plant.
