The Mind-Blowing and Dynamic Winterthur Viburnum 

Winterthur Viburnum, also known as Viburnum nudum 'Winterthur', is a deciduous shrub that blooms with white flowers in the spring and has dark green leaves that turn a beautiful red in the fall. While aesthetically pleasing, Winterthur Viburnum is also a great pollinator plant that can attract various types of pollinators to your garden.

Pollination Requirements

Winterthur Viburnum is a self-fertile plant, meaning it can produce fruit (berries) on its own without needing another plant for pollination. However, having multiple Winterthur Viburnum plants can increase fruit production and overall pollination in your garden.

Attracting Pollinators

Winterthur Viburnum can attract various types of pollinators, including bees, butterflies, and hummingbirds. Its flowers have a sweet scent and are open and accessible, making it easy for pollinators to access nectar and pollen.

Maintaining Pollination

To keep your Winterthur Viburnum plant healthy and thriving, it's important to provide regular watering and fertilizer. Adding organic material such as compost and mulch around the base of the plant can help with moisture retention and soil fertility. This, in turn, can help maintain pollination by providing a healthy environment for both the plant and its pollinators.
