Common questions
My dog ate lilac buds off the bush — is that fine?
Yes, they are non-toxic. At worst a large snack loosens the stool for a day.
Is California lilac (Ceanothus) also safe?
Ceanothus is a different plant but is also generally considered non-toxic. Just do not confuse either with Persian lilac, another name for toxic chinaberry.
