20. Daffodils (Narcissus spp.)
Daffodils bring cheer to indoor spaces with their bright yellow blooms, especially in early spring.
But their bulbs are highly toxic and can cause severe gastrointestinal symptoms—including vomiting, diarrhea, and abdominal cramps—if ingested by pets or children.
Even a small amount can trigger significant discomfort, and the risk is greatest when bulbs are within easy reach.
If you enjoy daffodils indoors, be vigilant about placement to ensure everyone’s safety.
