They're likely Indian Mock Strawberries. They have yellow blooms. They're edible, but taste like blah. They're an invasive species here in SC, and they're fairly difficult to remove.
If they have white/pinkish blooms, they may be wild strawberries or a small other variety. You'll be able to smell them, if so. They're pretty fragrant! And VERY tasty!
