Want winter colour and scent?
Viburnum are one of those undersung, but extremely useful groups of shrubs, that have representatives performing at almost every time of year whether through flowers, foliage or fruit.
The winter flowering varieties are especially welcome when little else is around. They can be deciduous or evergreen, with flowers produced in dense clusters, studding bare branches, or in flat heads among leaves, often sweetly scented.
Although Viburnum botnatense 'Dawn' is the most familiar, its worth looking out for 'Charles Lamont', which has stronger pink tones. The diminutive 'Nanum' form of the normally tall V.Farreri is a useful spreading shrub for the smallest borders. All the deciduous forms lend themselves to be under planted or associated with early bulbs and perennials, such as hellebores and associated with other winter-flowering shrubs, such as mahonia.
Most viburnums are indifferent to soil as long as it's not soggy or too chalky. They will grow in sun or shade, but will flower better in sunlight. Most need little of no pruning save to keep them in shape. Do this just after flowering.
