Also known as Florist's Chrysanthemum, Garden Mum, Ju Hua, Florist's Daisy
Florist's chrysanthemums display vibrant late-season flower heads ranging from rich burgundies and yellows to pristine whites, blooming when most other garden plants fade. Originating from centuries of selective breeding in East Asia, these hardy perennials rely on shortened day lengths to trigger their autumn flowering. Their dense, aromatic foliage contains natural protective compounds that deter insect pests while providing late nectar for pollinators.
Toxic to dogs and cats if ingested, and sap can cause skin irritation; observe safely.
Why it is dangerous
Contains sesquiterpene lactones, pyrethrins, and sap irritants that cause gastrointestinal distress and drooling in pets, as well as contact dermatitis in sensitive skin.
How to recognize a risky encounter
Look for deeply lobed, strongly scented aromatic leaves paired with dense, multi-petaled late-season flower heads.
What to do
Wear gloves when deadheading or handling cut stems, and keep indoor potted cultivars out of reach of domestic pets.
Responsible observation
Pinch Stems Early: Prune back growing tips in early summer to encourage bushy growth and a heavier autumn floral display.
Wear Gloves: Handle stems and cut flowers with gardening gloves if you have sensitive skin to avoid potential skin irritation.
Protect Pets: Keep curious dogs and cats away from garden beds where foliage or fallen flower heads could be ingested.
