If you have Viburnum growing on your property of your neighbors property, it is likely that those Viburnum will be sufficient to pollinate your Blue Muffin. If Viburnum is naturally rare in your area, it is advised to plant two or more of these in order for them to pollenate each other producing berries in fall.
Blue Muffin® Arrowwood Viburnum
Viburnum dentatum 'Christom'
Crisp white flowers adorn Blue Muffin® Viburnum in the early summer and give way for small blue berries which adorn the green foliage in the late summer season throughout fall. This North American native plant is a showy deciduous shrub that attracts songbirds with its vibrant blue berries, is deer resistant, and is easy to maintain. Some say two shrubs are necessary for pollination, but if there is any other viburnum nearby, you will not need an additional pollinator.
