The viburnums (Viburnum sp.) is a large genus with plants native to North and South America, Europe and Asia. Nearly all the species and cultivars are good landscape plants as they are relatively disease and pest free, have good form and foliage and generally have reddish fall color. The flowers are generally white and showy. Some of the viburnums do get mildew by late summer, especially V. prunifolium (blackhaw) and V. lentago (nannyberry). A few viburnums have fragrant flowers but those are generally not hardy in Minnesota. We have 13 species, and 20 cultivars and a total of 56 specimens.
