Brandywine Viburnum (Viburnum nudum 'Bulk') is a deciduous shrub that belongs to the family Adoxaceae. It is native to the eastern part of North America and is known for its showy white-pink flowers and attractive foliage.

The flowers of Brandywine Viburnum are primarily pollinated by bees, especially bumblebees, which are attracted to the sweet nectar produced by the flowers. In addition to bees, other pollinators such as butterflies and moths may also be attracted to the flowers.

Once the flowers are pollinated, they develop into round, pinkish-red fruit, which are attractive to birds and other wildlife. The fruits are also edible for humans, although they are not often consumed due to their sour taste.

To ensure optimal pollination of Brandywine Viburnum, it is important to plant it in a location that receives plenty of sunlight and has well-draining soil. Additionally, providing a source of water for pollinators can help attract bees and other beneficial insects to the plant.
