Laurustinus (Viburnum tinus) develops an upright-oval shape at maturity about 10 to 15 feet tall and 8 to 12 feet wide. This broadleaved evergreen fares best in U.S. Department of Agriculture hardiness zones 7b through 10, best where temperatures never drop below -12.2 degrees Celsius.

Overwintering Problems

Michael Dirr of the University of Georgia notes that even in winters with temperatures between -17.8 to -9.44 degrees Celsius, some laurustinus shrubs may sustain uneven or severe branch dieback. If fall frosts occur too early, youngest branch and leaf growth tends to succumb to cold.

Pests

Generally pest free, laurustinus tends to be eaten by hungry deer and viburnum beetles (especially in the Northeast or other scale insects appear if the shrub is stressed from drought, nutritionally poor soils or too little sunlight.

Diseases

Dirr notes that laurustinue is generally free of disease concerns. However, it does rarely succumb to sudden oak death, crown gall, anthracnose, Botryosphaeria canker and verticillium wilt. Other minor foliage disease nuisances include downy and powdery mildew.
