This one shows the three leaves that I grew up hearing about. “Leaves of three, let it be” was the saying I learned in Girl Scouts.
It is the urushiol oil that is the culprit. The oil can linger on animal fur, on car seats, clothing, and tools and just about anything. So while I don’t have to worry I need to take care that I don’t spread the oil around for my unsuspecting friends to come in contact with. If it is not washed off within about three minutes after exposure it will be absorbed into the skin and a rash will occur.
In my neck of the woods we also have Virginia Creeper which looks a lot like poison ivy. Here you can see the difference between the two vines. The creeper has bigger and lighter colored tendrils compared to the dense hairy ones of the Poison Ivy.
