Winterthur Viburnum (Viburnum nudum 'Winterthur')

Winterthur Viburnum (Viburnum nudum 'Winterthur') Pollination Info:

Winterthur Viburnum is a deciduous shrub that produces small clusters of creamy white flowers in the spring. These flowers are self-fertile, meaning that the plant can pollinate itself and produce fruit without the need for another nearby pollinator.

The flowers are attractive to bees, butterflies, and other pollinators, which help transfer pollen between flowers for better fruit production. Planting multiple Winterthur Viburnum shrubs can increase the chances of successful pollination and fruit set.

After pollination, the plant produces small, oval-shaped berries that start off green and turn shades of pink, red, and blue as they ripen. These berries are a food source for birds and other wildlife.

Overall, Winterthur Viburnum is a reliable and low-maintenance shrub that typically does not require special pollination considerations for fruit production.
