Winterthur Viburnum
Viburnum nudum 'Winterthur'Winterthur Viburnum is a beautiful native shrub prized for its glossy green foliage, abundant clusters of white spring flowers, and vibrant fall berry display. In late spring, large rounded clusters of fragrant white blooms cover the shrub, attracting honey bees, butterflies, and other beneficial pollinators. After flowering, the shrub develops clusters of berries that transition from green to pink and blue before maturing to deep blue, providing an important food source for birds in the fall and winter.
Its glossy foliage remains attractive throughout the growing season before transforming into shades of yellow, orange, red, and purple in autumn. This exceptional fall color, combined with its colorful berries, makes Winterthur Viburnum a standout multi-season shrub. The dense, rounded habit provides excellent structure and natural beauty in the landscape while supporting local wildlife.
Growing approximately 6 to 10 feet tall and wide, Winterthur Viburnum performs best in full sun to partial shade and thrives in moist, well-drained soils. It is especially valuable for areas where a native shrub is desired for woodland edges, rain gardens, naturalized plantings, and mixed borders. Its ability to tolerate wetter soils makes it a dependable choice for landscapes with moisture challenges.
