Following on from my recent post about houseplants that are toxic to dogs, I thought it might be useful to point out that the berries on some popular garden plants are toxic to humans. While everyone would recognize a blackberry and know it as a useful fruit, some other berries which look inviting are definitely not for human consumption. I found this list in an article by Melissa Will on her Empress of Dirt website.

Many?plants have medicinal qualities which can be toxic to humans or pets and many of them grow in our gardens without ever causing a problem. You have to decide for yourself whether they may actually pose a problem for you or your beloveds.
Nature?s built-in warning system is that harmful plants and berries have repulsive tastes. I?m not sure if there?s exceptions to this, but overall, if it takes like poison, it is.
Some plants have poisonous berries that are only harmful when impossibly large amounts are ingested. Others, like Virginia creeper, are much more damaging even in small doses?and can be fatal if eaten.
Here?s some common plants with poisonous berries.
1. Oriental Bittersweet (Celastrus orbiculatus)
The flowers, fruits, and seeds are poisonous to humans, cats, and dogs if ingested.
