FAQ

Lodense Privet, Ligustrum vulgare, have white odorous flowers and black berries are attractive and palatable for birds, however the berries and parts of the plants are poisonous to mammals, including cattle, cats, dogs, and humans. 

I looked under the FDA Poisonous Plant Database (http://www.cfsan.fda.gov/~djw/plantox.html)  for privet.  This database contains references to the scientific literature describing studies of the toxic properties and effects of plants and plant parts and 92 records, which could be articles or studies that show toxic properties of privet.

Please note, that they are several ornamental plants that can be toxic to mammals, and I appreciate your question and good judgement should be used when selecting plants for our landscapes.

If you have any further questions, please feel free to contact me.
