Uses and benefits of Snowberry – Symphoricarpos albus

The fruit and shrub itself is high in saponins, which are mildly toxic to humans and pets causing vomiting, but very beneficial for birds, butterflies, and other wildlife. This shrub is used for erosion control in riparian areas, and it is planted in ecological restoration projects on disturbed sites such as abandoned mines. Its white fruits and blue-green foliage made it popular as an ornamental plant planted around old houses of the 1890s through the 1920s like with the Vanhoutte Spirea or Bridalwreath.

Plant Description

Snowberry is an erect, fast-growing densely-branched, deciduous shrub that normally grows about 1–2 m (3.3–6.6 ft.) tall. The plant is found growing in banks and flats in canyons,  near streams below, thickets, forest edge, open slopes, lowlands to middle elevations in the mountains, mesic to dry meadows, disturbed areas, grasslands, shrub lands, steppe and montane, riverbanks, rocky slopes, riparian areas, roadside embankments, railroads, and rocky waste area. The plant prefers well-drained, heavy soils (clay) and areas that provide enough sun. It is naturalized in parts of Britain, where it has been planted as an ornamental and a cover for game. The plant produces stiff, branching main stem and often several smaller shoots from a rhizome. It can spread and colonize an area to form a dense thicket. Twigs are slender and yellow-brown. Yellowish-brown bark are found on young shoots while bark on older stems and twigs are grayish-brown and scaly or split lengthwise on older shoots.

Leaves

Pairs of opposite deciduous leave occur along the twigs and young shoots. These leaves are ½ to 1½ inches long, up to 1 inch wide. They are usually oval-elliptic to egg-shaped to nearly round, blunt to round at the tip, mostly rounded at the base, on a short, finely hairy stalk and their margins are usually smooth or slightly undulate (leaves of very young shrubs are sometimes more undulate). The upper surface is hairless to sparsely hairy, dark green to blue-green, while the lower leaf surface is light green to nearly white and hairless. The petioles of the leaves are very short up to ¼ inches in length; light green, and hairless to slightly short-pubescent. New twigs are yellowish to reddish brown, finely hairy when young becoming hairless.

Flower

The inflorescence is a terminal cluster of up to 16 flowers at the ends of new stem growth. The flowers are about 1/4 inch long with a bell shaped pinkish-white corolla. The five corolla lobes have obtuse tips but the lobes do not spread, making the flower appear longer than wide. This is unlike Wolfberry where the lobes spread widely. The green elongated calyx has 5 triangular shape lobes that have a purplish tinge. The inside of the corolla is bearded with white hairs; the reproductive parts have 5 stamens and a style. The inferior ovary is ovoid in shape, but somewhat constricted at the base of the calyx. The light green pedicels of the flowers are very short (less than 1/8 inches or 1–2 mm. long), while other stalks of the inflorescence are light green to reddish purple. The blooming period typically occurs from early to mid-summer for about 1½ months, although it may become extended into autumn under favorable conditions. Flowers have an unpleasant odor.

Fruit

Fertile flowers produce a globoid, fleshy, bright white drupe, about 1/3–2/3 inches (8–16 mm.) across in diameter, with a waxy surface texture. Like the flowers, these will be in a small cluster, which will last into the winter as birds do not usually eat them in the autumn. Each drupe has a waxy-fleshy interior with a bitter flavor and a pair of seeds or sometimes 3.  Spongy berries when squeezed have 4-5 mm. long, bony white, flattened, broadly ellipsoid seeds surrounded by a pulpy flesh. The fruit ripens from September to November. With proper storage, seeds are viable for 7 to 10 years. The plant sometimes reproduces via seed but it is primarily vegetative, reproducing by sprouting from its spreading rhizome. Birds disperse the seeds after they eat the fruit. They are non-edible to humans and toxic due to the saponin they contain.
