Bob, this looks like the leaf to "Deadly Nightshade" It gets small purple blooms and red berries in the fall. Although poisonous, we don't usually go around eating things,and if you don't have small children, I wouldn't worry. To my knowledge it has never been invasive, but at times I have even let it grow on purpose because it's rather pretty. :) Arum

Before learning they are poisonous, I ate a berry, and nothing happened. I think an adult would need to eat a lot of berries to get sick. They grow wild around here, and I think they are attractive, so I let some of them stay.
