This small deciduous shrub is covered in early spring with pink buds that burst open to reveal slightly fragrant, showy, flat-topped white flowers. Fleshy red fruit is borne in pendulous bunches in late August, darkening to all-black in October. Leaves fade to a dark maroon in the fall and winter months when planted in colder areas. Plants grow to about 5 feet tall and 8 feet wide. A cross between V. utile and V. × burkwoodii ‘Park Farm Hybrid’, this shrub is excellent as a foundation plant, as a specimen, in mass groupings, in a shrub border, or in containers. Evergreen to Zones 7 and 8.

This variety has single, papery white blossoms that open from light pink buds and have contrasting yellow stamens. The heavily-scented flowers are followed by reddish-orange hips. It grows up to 6 feet high.
