This attractive selection of native Smooth Witherod Viburnum offers exceptional three-season interest while providing valuable food and habitat for birds and beneficial wildlife.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIn late spring to early summer, Winterthur produces an abundance of flat-topped clusters of delicate creamy-white flowers that attract bees, butterflies, and other pollinators. When planted near a compatible, genetically different Smooth Witherod Viburnum, the flowers develop into beautiful clusters of ornamental berries that transition from green to pink and eventually deep blue to purplish-black. Multiple berry colors may appear on the same plant, creating a particularly attractive late-summer and fall display.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThroughout the growing season, Winterthur maintains lustrous, dark green foliage and a naturally rounded, upright growth habit.
