Understanding Poison Sumac and Its Characteristics
Poison sumac thrives in wet areas across the United States. It’s a unique plant with distinct features that set it apart from poison ivy and oak3.
Poison sumac typically grows as a small tree or tall shrub in swampy regions. It can reach up to 20 feet in height3. The plant’s appearance changes with seasons, displaying vibrant colors throughout the year.

The Dangerous Urushiol Oil
Poison sumac’s real threat comes from its urushiol oil. This toxic substance causes severe allergic reactions. Just 50 micrograms of this oil can trigger a painful rash3.
