Growing beside the road in from of our house.
Under large old white oak.
Dies back in winter.
this is a commonly grown groundcover flower known as periwinkle, and this is a variegated variety. It is robust, so I would call it Vinca major. More commonly grown is Vinca minor which is essentially completely prostrate. In a second image that you sent you also had a wild black cherry tree in flower, Prunus serotina. Periwinkle is an introduced plant and it can spread quite a bit. It is usually evergreen, however.
