CAUTION: MAY HAVE INVASIVE TENDENCIES. Cornus mas, or cornelian cherry, is a low-maintenance, non-native dogwood from Asia and Europe, known for its excellent resistance to dogwood anthracnose and the dogwood borer. It prefers well-draining loam soil with a slightly acidic to neutral pH. It generally faces few pest or disease issues, though it can become vulnerable to borers if stressed. Pruning should be done in spring after flowering to maintain its health.
