poison ivy
Rash-causing climber
Poison ivy is a North American plant whose leaves cause an intensely itchy rash on contact.
The irritant oil affects most people, making the plant notorious among hikers and gardeners.
I got poison ivy all over my arms clearing brush.
The three-leaflet pattern prompts the warning "leaves of three, let it be."
