Dawn viburnum

Sun

Full sun or partial shade; flowering is usually best with plenty of sun. Shelter from cold, drying winds.

Water

Keep the root zone evenly moist while establishing. Once established, water deeply during prolonged dry spells, particularly in hot summers.

Soil

Moist but well-drained soil enriched with organic matter; tolerates clay, loam and chalk, and acidic to alkaline conditions. Avoid persistently waterlogged ground.

Height

8-10 ft (2.4-3 m)

Spread

6-8 ft (1.8-2.4 m)

Flowers

Winter to early spring, sometimes starting in late autumn in mild climates. Deep pink buds open to fragrant pale pink flowers that fade towards white; flowering is later and more concentrated in cold climates.

Foliage

Opposite, oval, toothed leaves emerge bronze, mature dark green and may turn burgundy or purple-red in autumn.

Growth rate

Moderate

• Plant when the ground is workable, setting the top of the root ball level with the surrounding soil.
• Water deeply through the first two growing seasons whenever the root zone begins to dry.
• Apply 2-3 in (5-8 cm) of organic mulch in spring, keeping it clear of the stems.
• On poor soil, apply a balanced slow-release shrub fertiliser in spring; avoid heavy feeding.
• Leave enough space for its mature width rather than controlling it with repeated shearing.

Pruning. Prune just after flowering, removing dead, damaged or crossing branches and shortening awkward shoots to a suitable side branch. To rejuvenate an established shrub, remove up to one-third of the oldest stems at ground level each year rather than cutting the whole shrub back at once.

Winter

Enjoy the scented flowers; check that nearby paths give access without brushing against the flowering branches.

Early spring

After flowering finishes, remove damaged wood and thin selected old stems if needed.

Spring

Renew the organic mulch and feed lightly only if soil is poor or growth is weak.

Late spring

Inspect leaves for viburnum beetle larvae and aphids; remove small infestations by hand.

Summer

Water during extended dry weather; take semi-ripe cuttings if you want more plants.

Autumn

Plant new shrubs while soil is moist and workable; in very cold climates, postpone planting until spring.

• Beside an entrance or winter-used path, with enough clearance for the mature branches, to bring the scent within reach.
• At the back of a mixed border, where summer perennials can provide interest after flowering ends.
• Against a dark evergreen backdrop that makes the pale winter flowers easier to see.
• In a winter-interest planting with snowdrops, hellebores and coloured-stem dogwoods.

Garden styles it suits: English country, Cottage garden, Woodland, Sensory garden, Winter interest and Traditional.

Plant it with: Snowdrops, Hellebores, Winter aconites, Witch hazel, Red-stemmed dogwood and Epimediums.

Wildlife: The flowers can feed bees and other insects active during mild winter or early spring weather. Its branches provide cover for small birds; fruit production is often sparse.

• Viburnum beetle can skeletonise leaves where it occurs, including parts of Europe and North America. Inspect in spring, remove larvae from small shrubs and prune out twigs bearing rows of egg pits during the dormant season.
• Aphids can cluster on young shoots and distort new leaves. Wash them off with water and allow ladybirds and other predators to control small colonies.
• Powdery mildew may coat leaves in dry, crowded conditions. Improve airflow, avoid overcrowding and water the soil during drought.
• Hard frost can brown open flowers. Choose a sheltered site and leave undamaged buds to open during the next mild spell.

Not known to be toxic to people, cats, dogs or horses. It is an ornamental rather than a food plant; do not eat any berries, and discourage pets from chewing it.

• Fragrant viburnum (Viburnum farreri)

  This parent of the hybrid also has scented pink-to-white flowers on bare stems. It generally has a finer, smaller-leaved appearance, but the two can be difficult to distinguish confidently without a reliable label.

• Bodnant viburnum 'Deben' (Viburnum × bodnantense 'Deben')

  'Deben' has flowers that are white or only lightly flushed pink, while 'Dawn' has more distinctly pink buds and newly opened flowers.

• Laurustinus (Viburnum tinus)

  Laurustinus retains its leathery evergreen leaves and carries broad, flattened flower clusters; 'Dawn' flowers mainly on bare deciduous stems.

The hybrid name bodnantense refers to Bodnant Garden in Wales, where this cross was raised.

Propagation. Take semi-ripe cuttings in summer or layer a low branch. Use vegetative propagation to retain 'Dawn'; seedlings will not reliably match the cultivar.
