Description and Growing Information

General DescriptionDeciduous upright standing shrub that is widespread. Spreads by using rhizomes and likes full sun to partial shade. A North American native with interesting pink/purple berries.
ID CharacteristicTwiggy branch growth with leaves opposite and bunches of almost completely globular pink/purple berries. Colonizes in forested areas through spreading of rhizomes.
ShapeUpright, twiggy, broad and rounded. Arching branches give the plant a lanky presence.
LandscapeUsed as a groundcover, background shrub or separation between landscape spaces. Tolerates shade well. Can be used as a hedge but needs to be densely planted as it does not grow very tall. The berries offer a nice touch of colour to the landscape as well as attract birds that are partial to eating sour berries.
PropagationSeed or cuttings. A bath of sulfuric acid for about 60 minutes, afterwards, warm temperatures followed by cold stratification should assist with speeding up and breaking seed dormancy. Cuttings root readily in summer months.
CultivationSoil tolerance for this plant is very high and can be transplanted without worry. Being native to Eastern North America, rock and clay substrate work well. Abundant spreading of rhizomes is an indicator of a vigorous plant.
PestsAnthracnose, berry rot, leaf spot, and rust.
HabitatShady forests and field edges.
Bark/Stem DescriptionSmooth and light brown on young plants and slightly darker and quite exfoliated bark on older specimens. Segregation of bark is unpredictable. Grows shaggier over time.
Flower/Leaf Bud DescriptionAxillary buds are protected by short spikes and are partially hidden. About 2 mm in length and somewhat scale-like, slightly pointed.
Leaf DescriptionSimple leaves 4-5 cm in length that are oppositely arranged and entire in shape. Leaves sometimes appear to be sessile.
Flower DescriptionPerfect 5 petal (Dicot) blooms which are 5 - 10 mm long and 5 - 8 mm in diameter. Yellowish white to pink in colour. Inconspicuous in form. Flowers occur on current year’s growth at the meristems which are protected by short spikes.
Fruit DescriptionDrupes in groups of 5 - 15 with an ovoid shape that are sometimes lumpy. Pinkish purple to deep red. Mostly globoid, bearing resemblance to snowberries though a little smaller. 5 - 10 mm diameter. Fruit persist until November.
Colour DescriptionDull green leaves with bluish-green undersides. Leaves can achieve a certain amount of autumn colour but isn’t notable. Coral-purple berries are the best physical attribute to this shrub. Light to medium brown, shaggy and exfoliated bark. Fungus on berries adds greyish-brown hues when present in later months of autumn.
Texture DescriptionMedium texture for most of the year, except for in winter when all its leaves are shed. The twiggy branches can look somewhat disheveled. Possible to manipulate branches through braiding/weaving in autumn or early spring.
