Description
Cornus alba ‘Kesselringii’ is a striking dogwood, grown for its dramatic, deep purple-black stems that provide bold winter colour and architectural interest. As the leaves fall, the bare stems become a standout feature—especially effective against pale backgrounds, evergreens, or when planted alongside other colourful dogwoods.
In spring and summer, ‘Kesselringii’ forms a bushy mound of mid-green foliage, producing clusters of small, creamy-white flowers followed by white berries that attract birds. The leaves turn rich shades of purple and red in autumn, adding another season of colour before the stems take centre stage.
This dogwood is highly adaptable, thriving in a wide range of soils—including damp or heavy ground—and is ideal for borders, waterside planting, or as a vibrant winter feature in mixed shrub beds. It’s also excellent for mass planting and wildlife gardens, where its structural value and seasonal changes truly shine.
Caragh Garden Notebook
Planting:
Space plants 1.5–2m apart for a dense effect or use singly as a specimen. Plant container-grown specimens in spring (March–May) or autumn (September–October). Choose a sunny to lightly shaded spot—full sun gives the richest winter stem colour. Dig a generous hole, loosen the soil well, and incorporate compost or well-rotted manure to support establishment. Plant at the same depth as in the pot, firm in gently, water thoroughly, and mulch.

Soil Preparation:
Prefers moist, well-drained soil but is very tolerant, including heavy clay or poorly drained ground. Mulch annually to conserve moisture and feed the soil.

Seasonal Care:
For the best winter colour, prune hard in late winter or early spring—cut back a third to two-thirds of the stems to near ground level to encourage strong new growth. Remove any dead, weak, or crossing branches. Water during dry spells in the first year.

Pests & Problems:
Generally trouble-free. Watch for occasional leaf spot or aphids. Good hygiene and air circulation help prevent issues.

Design Notes:
Superb for winter colour in borders, as a specimen or in groups. Pairs beautifully with yellow- or red-stemmed dogwoods, evergreen shrubs, and spring bulbs. Excellent for waterside planting, wildlife gardens, and low-maintenance schemes.
