The plant is native to northeastern and Midwestern United States and to southern Canada from New Brunswick west to southeastern Saskatchewan. It can also be found in the Dakotas, Wyoming, Colorado, and the Appalachian Mountains as far south as Kentucky and Virginia. Although widespread in eastern North America, this plant is only known to exist in Missouri in low woods and wooded slopes in Schuyler County. Nannyberry, Sweet Viburnum, Blackhaw, Wild Raisin, Sheepberry, Black Haw, Cowberry, Nannyberry Viburnum, Nanny Plum, Sweetberry, and Tea Plant are some of the popular common names of the plant.

Nannyberry Quick Facts
Name: Nannyberry
Scientific Name: Viburnum lentago
Origin Northeastern and midwestern United States, and to southern Canada from New Brunswick west to southeastern Saskatchewan
Colors Initially, green turning to red and maturing to blue or black.
Shapes Edible, juicy, berry-like, and ellipse-shaped to nearly spherical, somewhat flattened, 8–16 mm (0.31–0.63 in) long drupe
Taste Sweet
Health benefits Beneficial for measles, painful urination, irregular menstruation, nervous irritation, muscular spasms, cramping, relieves , relieves anxiety, respiratory and digestive problems

Genus name comes from the Latin name of a species plant. Specific epithet means flexible as the twigs are very tough and flexible. Nanny goats apparently feed on the ripe berries (reportedly more so than billy goats), hence the common name. The plant is also known as “sheepberry” because its fruit smells like wet sheep wool when over ripe. Nannyberry is a shade-tolerant, understory species useful in landscape plantings as shrub borders, taller barriers, hedges, and windbreaks. It produces good seasonal displays of flowers, fruits, and fall leaf color. The fruits are sweet and edible and are eaten by many species of birds and wildlife.

Plant Description

Nannyberry is a deciduous, multi-stemmed shrub or small to the medium-sized deciduous tree that normally grows about 9 m (30 ft.) tall with a trunk up to 25 cm (10 in) in diameter. The plant is found growing in rocky woodlands, mesic woodlands, low woodlands along streams, thickets, roadsides, and fence rows, borders and banks of streams and rivers, fens, sedge meadows, tamarack swamps, shrubby swamps, swamps, borders of the forest, fence corners, rocky hillsides, swamp borders,  upland woods, hardwood forest edges, flood plains, and lakeshores. The plant grows best in a rich, moist area with clay-loam soil. It can tolerate both acid and alkaline soils. The plant rises from scattered, deep, anchoring roots and shallow, branched, fibrous, soil-binding roots. The roots have buds that may sprout and form above-ground stems (suckers). When conditions permit, it forms colonies that may become large and dense. Nannyberry is leggy and somewhat open at maturity with an irregular to rounded crown. Suckers often form at the base.

Twigs

Twigs are slender, long, flexible, and round or somewhat six-sided. First-year twigs are pale green and covered with downy, rust-colored hairs at first, becoming gray or dull grayish-brown, smooth, and hairless. Second-year twigs are brown to reddish-brown or grayish-brown and maybe somewhat covered with a whitish, waxy bloom (glaucous). The twigs have an unpleasant odor when bruised. The pith is white and solid. The leaf scars are narrow, crescent-shaped, and slightly raised. Each leaf scar has three bundle scars. The terminal bud is brownish-gray, hairless, ¾ inches to 1¼ inches long, oblong cone-shaped, and somewhat flattened, with a swollen, bulbous base and a long, tapered tip. It is covered by two sharply pointed, abutting but not overlapping, sharply-pointed scales. Lateral buds are about half as long, are not swollen at the base, and are often curved.

Bark

The bark is grayish-brown and smooth at first, becoming rough and shallowly furrowed with irregular, scaly plates with a few warty bumps and becoming scaly with age. Young stems can also have a rusty-brown downy appearance. When broken, the bark has a skunk-like odor. The flower buds that form on the tips of last year’s twigs are distinctive with a round base tapering to a long pointed spire.

Leaves

Leaves are opposite, undivided (simple), and deciduous. They are attached to the twig on a ⅝ inches to 1¼ inches long leaf stalk (petiole). The petiole is channeled on the upper side and has conspicuous wavy wings. It is moderately to densely covered with microscopic, red, star-shaped hairs when young, becoming hairless or nearly hairless at maturity. There are no projecting glands near the attachment of the leaf blade. There are no leaf-like appendages (stipules) at the base of the petiole. The leaf blades are relatively thin, broadly egg-shaped to elliptical or broadly elliptical, 2 – 4 inches long, and 1⅜ – 2⅜ inches wide. They are rounded or broadly tapered at the base and taper to a short, sharp point at the tip with concave sides along the tip. They are pinnately veined. The lateral are evenly spaced, curve toward the tip, and form a network with adjacent veins without reaching the margin. The upper surface is dark green or yellowish-green and glossy, with scattered, microscopic, red, star-shaped hairs when young, becoming hairless at maturity. The lower surface is pale green with tiny, dark brown dots. The margins have more than 25 fine, sharp, forward-pointing teeth on each side. The leaves turn red or reddish-purple in the fall.

Flower

The inflorescence is a dense, rounded, shallowly convex, 2 – 4 inch in diameter, branched cluster (cyme) at the ends of the current-year branches. The cymes have usually 3 to 5, sometimes up to 7, main branches originating from the tip of the branch. Each cyme has a few hundred to several hundred small flowers.

Flowers are 1/8 – 5⁄16 inches in diameter. There are five sepals, five petals, five stamens, and no style. The sepals are green, fused for most of their length into a minute cup (calyx), and separated at the tip into five-minute, egg-shaped lobes. The petals are pale yellow to creamy white, egg-shaped to elliptical, and 1 ⁄16 – 1/8 inches long. The stamens have white filaments and bright yellow anthers. They are 1/8 – 3 ⁄16 inches long, longer than the petals. There is a three-lobed, stalkless stigma on a short disk (stylopodium) at the top of the . The flowers on the margin are fertile and are similar in appearance and size to the other flowers. The flowers are not fragrant. Flower stalks are hairless and green to red. They appear in mid-May to early June.

Fruits

Fertile flowers are followed by edible, juicy, berry-like, and ellipse-shaped to nearly spherical, somewhat flattened, 8–16 mm (0.31–0.63 in) long drupe that hangs from the reddish stem. The fleshy interior of each drupe is somewhat juicy and sweet, tasting like a raisin or date. drupes consist of a single large stone seed that occupies much of the volume of the drupe. The stone is oblong oval, flattened and dark-colored. The fruit is initially green turning to bluish-black and glaucous at maturity. The calyx and stigma persist in fruit, forming a dried tip at the end (apex) of the drupe. The pedicels turn red as the fruit matures. The fruit ripens in late August to late September, often remaining on the plant through the winter.

The ripe fruit is eaten by many birds and animals usually after it has frozen and thawed as the fruit then turns sweet. Overripe fruit smells like wet sheep wool, hence one of the alternate common names of Sheepberry. Humans will find the fruit barely palatable. Cooking has not found it any better.
