These are all over my back yard. Poison oak?
Not poison ivy or poison oak. It looks familiar but it's just not clicking at the moment. I'm sure someone will offer up an ID in short order.
I think it is Aegopodium podagraria (Bishop's Weed.) You normally would see the variegated version in gardens, and even though variegated is still pretty aggressive so I can see the plain green one being all over yard.
I think remy is correct.
