These plants have been known to be harmful to animals and people.  We recommend you research what's in your yard, and what you're going to add to your yard, specifically if you have little ones or furry ones. This is not a comprehensive list, but we've tried to gather the most comprehensive list possible.  We sell many of the following varities of plants and believe that mother nature made each of these plants for a reason, and as gardeners have the power to research whether the plants are suited for our homes and lives.

And remember: Just because something is on the poisonous plants list doesn't mean it can't be a good food or feed, and just because it is absent from the list doesn't mean it is safe!

Edible plants to be cautious around:

  • Tomatoes (the leaves are poisonous)
  • Grapes (harmful to pets)
  • Mushrooms
  • Black walnuts
  • Onions (careful around dogs)
