Black chokeberry

Sun

Full sun to partial shade; flowering, fruiting and autumn colour are usually best in full sun.

Water

Moderate; keep evenly moist while establishing. Established plants tolerate periodic waterlogging and some dry spells.

Soil

Adaptable to clay, loam and sandy soils, preferably moist and acidic to neutral. Strongly alkaline soil can cause yellowing leaves.

Height

3-6 ft (0.9-1.8 m)

Spread

3-6 ft (0.9-1.8 m), eventually wider if suckers are retained

Flowers

Clusters of small white, sometimes pink-tinged flowers in mid to late spring.

Foliage

Glossy, finely toothed green leaves turn orange, red or purple in autumn.

Growth

Slow to moderate

Care needed

Low

• Water deeply during dry spells through the first two growing seasons.
• Apply a 2-3 in (5-8 cm) layer of organic mulch, keeping it clear of the stems.
• Feed only if growth is weak; a light spring application of compost is usually sufficient.
• Remove unwanted suckers at their point of origin to keep the shrub within bounds.
• Protect ripening fruit with taut, wildlife-safe netting if you want a harvest.

Pruning. In late winter, remove dead or damaged wood and thin crowded plants by cutting a few of the oldest stems to ground level. Avoid routine shearing, which removes flowering wood and reduces fruit.

Autumn

Plant while the soil is workable, water thoroughly and mulch; in very cold regions, spring planting is also suitable.

Late winter

Thin old stems if needed and remove unwanted suckers.

Spring

Refresh mulch and check that newly planted shrubs remain moist.

Late spring

Leave flowering branches untrimmed so pollinators can visit and fruit can develop.

Summer

Water young shrubs during dry weather and check foliage for mildew or feeding damage.

Late summer to early autumn

Harvest fully black, ripe fruit for processing, or leave it for wildlife.

• Plant as an informal hedge where its suckering habit can create a dense screen.
• Use in a rain garden or beside a pond, above permanently submerged ground.
• Combine with switchgrass and late-flowering perennials for autumn foliage and contrasting textures.
• Plant along a sunny woodland edge with other fruiting shrubs to provide wildlife cover and food.
• Include in an edible border for fruit used in juice, preserves or baking.

Garden styles it suits: Wildlife garden, Native meadow, Woodland, Native hedgerow, Edible landscape and Autumn colour.

Plant it with: Winterberry, Virginia sweetspire, Switchgrass, Blue flag iris and Cinnamon fern.

Wildlife: Flowers provide pollen and nectar for insects, including bees. Birds and some mammals eat the fruit, often later in the season, and established thickets provide shelter.

• Powdery mildew: improve air circulation, avoid crowding and water the soil rather than the leaves; light infections rarely need treatment.
• Leaf spots: collect badly affected fallen leaves and avoid overhead watering; established shrubs usually tolerate minor spotting.
• Yellow leaves with green veins on alkaline soil: test the soil pH and consider moving the shrub to a more suitable site rather than repeatedly treating symptoms.
• Unwanted suckering: cut or dig out new shoots regularly, or give the shrub room to form a colony.

Ripe fruit is edible for people and is not known to be poisonous. Black chokeberry is not generally regarded as toxic to cats, dogs or horses, although species-specific animal safety information is limited. Seeds contain cyanogenic compounds, so do not deliberately crush or consume seeds in quantity; eating large amounts of fruit can also cause digestive upset.

• Red chokeberry (Aronia arbutifolia)

  Has red rather than black ripe fruit, with noticeably hairy leaf undersides and young shoots.

• Chokecherry (Prunus virginiana)

  Usually grows taller and carries flowers and fruit in long, narrow racemes rather than the short, broad clusters of black chokeberry.

• Serviceberry (Amelanchier spp.)

  Its spring flowers have long, narrow petals and generally appear before or as the leaves open; chokeberry flowers have short, rounded petals and open after leaf emergence.

The species name melanocarpa means black-fruited, while chokeberry refers to the mouth-drying astringency of the raw fruit.

Propagation. Lift rooted suckers during dormancy, or take softwood cuttings in early summer. Seed needs cold, moist stratification and may not reproduce the characteristics of a named cultivar.
