Answer: You're right, the berry you see in holiday decorations is probably pepperberry (botanical name: Schinus molle). Unfortunately, this native of Peru is not hardy in your region. Other sources of red berries would be winterberry (Ilex verticillata), or a viburnum such as 'Oneida', which has red fruit that persists through late winter. Heavenly bamboo (Nandina domestica) also has red berries. It is hardy to zone 6 with protection, so you should be able to grow it in suburban Detroit, but probably not in other parts of the state.
