These shrubs are most commonly used as holiday decorations, although they can be found in gardens. Holly exposure accounts for the 3rd highest rate of genus-specific human plant exposure calls in 2010, with 877. The berries containing the toxin saponin are poisonous; the leaves are not.
Although ingestion is generally not fatal, consuming several leaves or berries are likely to cause gastrointestinal distress, such as vomiting and diarrhea. The small spikes present on each leaf often prevent your pet from ingesting large amounts, but they can also cause pain and swelling in the mouth area when chewed.

Like mistletoe and poinsettia, holly is prized for its beauty and feared for its rumored toxicity.

Its berries, which contain a caffeinelike alkaloid, might cause irritation, but a fatal ingestion is unlikely.
When drip-dried, you can use holly branches to decorate mantels, doorways, tables, and to make centerpieces. Holly will last a bit longer if branches are placed in a vase of water or if small pieces are floated in a large bowl of water. The decorating possibilities are many!
