Description and Growing Information

General DescriptionOriginal hybrid tends to be leggier than more recent cultivars. An interspecies hybrid developed in Holland by horticulturist G. A. Doorenbos.
ShapeA small to medium sized deciduous shrub. Tends to be rangy, with extended bowing branches. Cultivars of this hybrid have been bred to be rounder and more compact.
LandscapeNot as widely used in landscapes as some of the newer cultivars. Can be used in informal hedges, borders and ground-cover. Its dense suckering root system can help hold together sloping ground that may tend toward erosion.
PropagationCan be propagated by dividing basal shoots and transplanting. Semi-hardwood cuttings in autumn or softwood cuttings in summer. Semi-hardwood cuttings should be rooted in perlite only and softwood cuttings should be rooted in a mix of perlite and peat. Can also be propagated by seed. However, its seeds have a hard outer coating that makes it challenging to germinate without stratifying them by soaking in water- first at room temperature for 60 days, then at 5°C for 180 days.
CultivationCan be grown in full sun to part shade. Adapts easily to many soil types. It prefers Symphoricarpus’ native limestone, clay and ideally moist well-drained conditions.
PestsPowdery mildew, scale, anthracnose, ruts and berry rot. Resistant to deer as they dislike the berries’ bitter taste.
HabitatHorticultural origin.
Bark/Stem DescriptionYoung bark begins to shred as the shrub ages, giving it an exfoliating appearance.
Flower/Leaf Bud DescriptionBuds are petite with a profusion of protective bud scales.
Leaf DescriptionSmall lamina reach a maximum size of about 4 cm in length and 2.5 cm in width with a rounded tip and cuneate base. Petioles are around 2 mm and are covered in short hairs. 3 - 5 pairs of veins can be observed.
Flower DescriptionFlowers appear in clusters and are 2 - 3 mm in length. 4 - 5 petals on each bloom, each attached to a central stem by a short stalk. Flowers on new growth.
Fruit DescriptionBerries appear in compact bunches of 5 - 15 mm in size and vary in colour from pale whitish-pink to hot pink.
Colour DescriptionThe berries vary from pale whitish-pink to hot pink. The flowers can be white or pink. The leaves are a dark green to greenish-blue on the upper surface and have a slightly tomentose underside. The bark is a dark brown colour that tends to fade to grey as it ages.
Texture DescriptionMedium.
