It looks to be some sort of ground cover or ivy, but I have no idea what this is. Please help!
I don't know for sure but possibly Creeping Jenny, Moneywort (Lysimachia Nummularia).
Swedish ivy perhaps.
The smaller leaves probably belong to a chickweed.
Chickweed has cute, tiny white flowers, and it's edible -- but really, it's a weed.
