Moonflower (Ipomoea alba) Seeds and Puppy Safety: Bitter Seeds Deter Ingestion

A gardener with moonflower vine dropping many seeds is getting a puppy; asked if seeds are poisonous to pets.

Risk Assessment

Tom said all parts of Ipomoea alba are poisonous, but seeds are very tough, hard, and extremely bitter. Animals/children typically spit them out. Poisonings are rare, mostly in teens abusing seeds as drugs. Watch the puppy; if too interested, fence off the plant until older. Similar to castor bean danger but animals usually avoid.

Moonflower seeds are toxic but unpalatable; supervise puppy, fence if needed.
