Yup. I know that plant. That's a Skunk Cabbage (don't know the scientific name). If you break off a leaf (or step on one accidentally) it'll stink just like a skunk but not as strong. The similarity of odor is uncanny. I lived in a house, as a young child, that had a cemetary across the street and a swamp (salt marsh) out beyond the back yard. I'm quite familiar with skunk cabbages as a result.
