Live and learn. Nobody would eat a daffodil bulb on purpose, but if you do it's bad news.
Also,
- Some people are highly allergic to daffodil sap.
- Most other plants cannot tolerate daffodil or narcissus sap. They secrete something which prevents other stems from absorbing water. That's why you never see bouquets or vases with daff or narcissus cuttings shared with other flower or plant cuttings.
