While McCartney is considered an occasional wildflower it was once a prized introduction to the domestic garden but was allowed to escape and little or no efforts were made to retrieve it. Consequently it has become a pest in some areas like Louisiana and Mississippi. These are introductions from China and are generally accepted as flat primitive" roses.
