Viburnum Flower


Viburnum grows in moderately fertile, well-drained soil in partial shade or full sun. But there are some viburnums that prefer dry soil. Let’s look at the common varieties of viburnum, so that you would know what to choose for your garden.

What makes the species of viburnums similar to each other is the way that the flowers are clustered together very much like an umbrella. The cluster of flowers is called corymb or inflorescence.

Common Varieties of Viburnum

Viburnum Tinus or Laurustinus

Viburnum tinus is a robust, bushy evergreen shrub known for its conspicuous clusters of flowers, leathery leaves, and colourful berries. It grows up to 240cm in height and 180cm in width.

Viburnum tinus produces pale pink buds in winter that grows until the middle of spring. Masses of small, aromatic, white flower clusters are elegantly positioned above the leaves. The flower clusters are about 5-10cm in size. Because they are rich in nectar, viburnums attract bees, butterflies, and other pollinators. The flowers yield eye-catching metallic blue berries.

Viburnum tinus has oblong, glossy dark green leaves, making it a perfect choice for hedges, borders, and low privacy screens. It is a great asset in the winter garden because not only is it easy to grow and manage, but also because this long-flowering shrub blooms when almost nothing else is in bloom.

  • Location: Full sun or shade.
  • Soil: Well-drained and moderately fertile and humus-rich soil. It can adapt to clay or sandy soils if well-drained.
  • Watering:  Give ocassional water during dry months for best fruit and flower production. Once the viburnum tinus is established in its planting ground, it is drought-resistant.
  • Pruning: Prune to maintain its shape in early to the middle of summer. Do not remove dead flower heads as it will not produce berries.
  • Feeding:  Mulch yearly with compost or well-rotted manure.

What to Expect

Viburnums are very versatile and can adapt to any conditions, making them perfect for your garden. They rarely contract diseases, which makes them low-maintenance. The correct location of plants, sufficient air circulation, and good watering habits can prevent soil and airborne issues.

Viburnum berries


Armillaria root rot (also known as shoestring root rot or mushroom root rot) is a fungus that affects plant roots, which can lead to death. The leaves and stems will appear yellow and leaves may fall. The roots of viburnum will eventually get sicker. The whole process up to death can take many years. It is hard to tell though if it’s armillaria root rot because the symptoms are like that of other stresses like poor care and lack of water. 


The most common diseases of viburnums are fungal diseases of the leaves. Here are the three fungal diseases that affect viburnums:

  1. Downy mildew – the leaves develop spotted areas, which eventually die in spring. Keep the leaves as dry as possible to prevent downy mildew.
  2. Fungal leaf spots – the leaves develop small spots that develop into irregular reddish to grayish brown spots. These typically happen in wet, warm summer months. Keep the leaves as dry as possible to prevent fungal leaf spots.
  3. Powdery mildew – white dusty growth appears on the surfaces of leaves. Use fungicide or horticultural oil.

Branches and Bark

Characterised by wilted or dead leaves, botryosphaeria canker affects viburnum. The fungus bears fruiting bodies that show on the branches and bark as dark brown or black bumps. There is no treatment yet, but you can prune off the affected parts with clean pruners.
