Few things are as gorgeous, inviting, or peaceful as a garden — but some of the prettiest flora can also be deadly. It's important to be aware of the toxic plants and flowers you shouldn't have around your house, especially if you have young children or pets.
Even 'pretty' houseplants can be dangerous; just a nibble of some of these common garden plants or houseplants can cause serious health effects. Children may be attracted to the bright berries on some of them, and others can be deadly to pets, even if ingested in small amounts.
You may be tempted to plant these and just keep them away from young children and animals, but that's not always easy to do out in the garden or within your home — after all, you can't watch everyone all the time. Take a look at the plants below, and always do your research first.
If you think your child or pet has ingested these plants, call your doctor or vet immediately.

A member of the carrot or parsley family, hogweed can reach 15 to 20 feet tall at maturity, with leaves that are up to 5 feet wide, with thick stems and white umbrella-shaped flowers.
The invasive species contains furanocoumarins in its sap. When it comes in contact with skin and is exposed to sunlight, severe skin inflammation and painful blisters erupt. The blisters may last for months and cause long-term sensitivity to sunlight.
