Winter shrubs have two main requirements: flowers and fragrance. They have to stand the worst the winter can throw at them, and if their foliage is attractive and evergreen or if their autumn berries hang on into winter, so much the better.
Viburnums fit the bill and there is quite a choice. They fall into three distinct groups and it would be no bad thing if we had one plant from each. For fragrant flowers, the forms of twiggy and deciduous Viburnum x bodnantense stand out. The four or five varieties available are similar and you’ll be pleased with any named form. The pink buds open to scented white flowers at any time from November to March and occasionally all the way through.
