Nannyberry is Minnesota's largest native viburnum. In prairie habitats, it forms large thickets. As an understory plant in forested areas, nannyberry rarely forms thickets and is a smaller shrub with only a few stems. In the landscape, nannyberry is grown as a large, suckering shrub or a single- or multi-stemmed small tree. It is a durable and easy-to-grow plant throughout Minnesota because of its hardiness, its ability to grow in light or shade, and its adaptability across a wide range of soil textures, moisture levels, and soil pH. Its dense plant form makes this species well-suited for use in barriers, borders, hedges, or for screening or difficult sites. Other uses in the landscape include massing and naturalizing, to which it is ideally suited. The fruit is edible and can be used to make jams and jellies. The fruit is also attractive to birds and other wildlife. The flowers, bruised twigs, and over-ripe fruit are said to smell like wet sheep wool; keep this in mind as you site this plant in the landscape.
Nannyberry viburnum provides two seasons of interest: spring and fall. 2-4", dark green, glossy, and wavy foliage develops in spring from 1"-long, narrow, pointed buds. 3-4", round-topped clusters of small 5-petaled flowers emerge from large vase-shaped buds in May and June. In fall pendulous clusters of bluish black berries with bright red stalks create a colorful combination with fall foliage in tones of yellow, red, and purple.
