Add four-season interest to your landscape with Viburnum nudum 'Winterthur', a handsome native shrub prized for glossy summer foliage, creamy-white spring flower clusters, and a dramatic fruit display that shifts through multiple colors before maturing darker. In fall, the leaves turn rich red to red-purple, extending the show well after flowering.
Plant it where you can enjoy the late-season color and berries: as a specimen, in a mixed shrub border, or along a naturalized edge. At maturity it typically reaches about 7-8 feet tall (84-96 inches) with a broad, rounded shape, so give it space to develop its strong branching and full canopy.
For best performance, grow it in full sun to part shade. More sun generally increases flowering, fruiting, and fall color, while part shade is helpful in hotter sites. This viburnum appreciates consistently moist soil and adapts well to sites that stay evenly damp, including areas with periodic moisture, as long as drainage is not stagnant.
Water regularly during establishment, then mulch to keep roots cool and conserve moisture. Prune only as needed to shape the plant or remove crossing wood, and do major pruning right after flowering to avoid removing next season's buds. For the heaviest berry set, consider planting with a compatible Viburnum nudum pollinator nearby. Expect the best results with steady moisture, good air circulation, and a site protected from drying winds.
