9. Poison Sumac
The ninth poisonous plant on our list is the striking poison sumac—even its name tells you a lot about how toxic it is. This one might look like a typical, harmless small tree or shrub, but don’t be fooled—it’s dangerous!
You can find poison sumac in different areas, such as wetlands, wooded areas, and swamps, and you’ll recognize it by its oval-shaped leaves and white berry clusters. Never let kids near this poisonous plant—it’s definitely not a sweet snack!
Similar to poison ivy, this plant is rich in urushiol, an oily resin that can cause severe itching, burning rashes, and blisters upon contact. You’d better stay away from it because even the slightest brush against its leaves can lead to days of discomfort.
