Viburnum plicatum 'Lanarth' is one of the most elegant flowering shrubs you can grow, admired for its distinctive horizontal branching and breathtaking display of large white lacecap flowers in spring. The blooms are arranged in graceful tiers along the branches, creating a layered effect that makes this shrub a true feature in the garden.

Throughout summer, the flowers are followed by small red berries that mature to glossy black, attracting birds and adding seasonal interest. In autumn, the rich green foliage transforms into vibrant shades of burgundy, crimson and purple before falling, ensuring Lanarth delivers beauty across multiple seasons.

Perfect as a specimen shrub, woodland planting or mixed border feature, Viburnum 'Lanarth' combines graceful structure with year-round garden appeal.

How to establish your Viburnum ‘Lanarth’?

Plant Viburnum 'Lanarth' in a full sun to part shade position.

For best flowering:

Choose a site receiving at least half a day's sun.
Full sun generally produces the heaviest flowering and brightest autumn colour.
In warmer regions, some afternoon shade is beneficial.

How to maintain your Viburnum ‘Lanarth’ once established?

Water deeply once or twice each week during the first growing season.

Once established, Lanarth is reasonably drought tolerant but benefits from deep watering during prolonged dry periods, particularly through summer.

Mulching helps conserve moisture and keeps roots cool.

For healthy growth and abundant flowering:

Apply compost around the base each spring.
Feed annually with a balanced slow-release fertiliser formulated for flowering shrubs.
Avoid excessive nitrogen, which encourages leafy growth at the expense of flowers.

Very little pruning is required.

Prune immediately after flowering if shaping is necessary.

Remove:

Dead or damaged branches.
Crossing stems.
Older stems if rejuvenation is required.

Avoid pruning in autumn or winter, as this may remove the following spring's flower buds.

Lanarth has a moderate growth rate, gradually developing into a broad, elegant shrub with its characteristic layered branching habit.

Viburnum 'Lanarth' is highly frost hardy and performs exceptionally well throughout New Zealand.

During winter:

Apply mulch around the root zone.
Water only if conditions become unusually dry.
Allow the shrub to remain dormant naturally before fresh spring growth begins.

Lanarth is generally a healthy and low-maintenance shrub.

Occasionally monitor for:

Aphids
Scale insects
Powdery mildew in humid conditions

Good airflow and avoiding overhead watering help minimise disease problems.
