Common snowberry

Sun

Full sun to partial shade; tolerates deeper shade, but flowers and fruits less heavily.

Water

Water regularly during the first growing season; once established, usually needs extra water only during prolonged drought.

Soil

Adaptable to sandy, loamy, clay and chalky soils, from mildly acidic to alkaline; prefers reasonable drainage rather than permanently waterlogged ground.

Height

3-6 ft (0.9-1.8 m)

Spread

3-6 ft (0.9-1.8 m), eventually wider through suckering

Flowers

Small pinkish-white bells in clusters from late spring through summer, followed by white berries.

Foliage

Small, opposite, oval green leaves; vigorous shoots may carry lobed leaves. Autumn colour is usually inconspicuous yellow-green.

Growth

Moderate to fast

In the garden

Spreads vigorously: plan to contain it.

Growth rate

Fast

• Water deeply during dry spells in the first growing season.
• Apply a 2-3 in (5-8 cm) organic mulch in spring, keeping it clear of the stems.
• Avoid routine feeding; use a little compost in spring if growth is weak on poor soil.
• Dig out unwanted suckers with their connecting roots before the colony expands.
• Leave enough room for arching stems rather than repeatedly clipping the shrub into a tight shape.

Pruning. In late winter or early spring, remove dead stems and cut up to one-third of the oldest stems to ground level. An overgrown shrub can be cut back hard at this time, though it may produce vigorous suckers.

Autumn

Plant while soil is workable, water thoroughly and mulch around the root area.

Winter

Leave berry-bearing stems for seasonal interest and birds.

Late winter

Thin out old stems and remove dead or damaged growth before new leaves emerge.

Spring

Refresh mulch and lift rooted suckers for propagation or removal.

Summer

Water young plants during dry spells and check the edges of the planting for unwanted suckers.

Late summer

Avoid clipping off developing berries if winter display is the main aim.

• Plant as an informal hedge where its suckering growth can form a dense screen.
• Use along woodland edges with ferns and shade-tolerant groundcover for a layered planting.
• Combine with red-twig dogwood so white berries contrast with coloured winter stems.
• Mass on roomy banks for soil cover, allowing access to control spreading shoots.

Garden styles it suits: Woodland, Wildlife garden, Native hedgerow, Winter interest, Low-maintenance and Rewilded.

Plant it with: Red-twig dogwood, Oregon grape, Red-flowering currant, Western sword fern and Bigroot geranium.

Wildlife: Flowers provide nectar and pollen for bees and other insects. Dense stems offer shelter, and some birds eat the berries, often later in winter when other food is scarce; it is native across much of the United States and Canada.

• Unwanted suckers: dig out shoots with their connecting roots, repeating as needed; avoid planting beside sensitive natural habitats outside its native range.
• Powdery mildew: thin crowded stems for airflow and water the soil during drought rather than wetting the foliage.
• Leaf spot: collect badly affected fallen leaves and avoid overhead watering; established plants usually tolerate minor spotting.
• Sparse berries: move to a brighter position if heavily shaded and avoid repeated summer clipping, which removes flowers and developing fruit.

The berries are not edible and can cause nausea, vomiting and diarrhoea in people, cats and dogs; most reported human poisonings are mild. Keep berries away from young children and pets. Information on toxicity to horses is limited, so do not assume it is safe as forage.

Where it spreads. Spreads vigorously by suckers. Outside its North American native range, it is invasive in parts of the United Kingdom and Ireland and parts of continental Europe, where dense colonies can displace woodland and hedgerow vegetation. Avoid planting near natural habitats in these regions.

• Coralberry (Symphoricarpos orbiculatus)

  Produces small pink to purplish-red berries clustered along the stems rather than the larger white berries of common snowberry.

• Western snowberry (Symphoricarpos occidentalis)

  Usually has larger, thicker leaves and more crowded terminal flower clusters; its bell-shaped flowers have conspicuously hairy interiors. White-fruited plants can be difficult to separate without flowers.

• Hybrid snowberry (Symphoricarpos × doorenbosii)

  Many garden selections bear pink or pink-flushed berries in heavy clusters. White-fruited selections can closely resemble common snowberry, so a reliable nursery label may be needed.

Symphoricarpos comes from Greek words referring to fruits borne together, while albus means white, describing the berries.

Propagation. Lift rooted suckers in autumn or early spring and replant promptly. Softwood cuttings in early summer or hardwood cuttings during dormancy are also suitable.
