Viburnums are related to the honeysuckles, so it should come as no surprise that many of them have fragrant flowers. But that's not all they have in their favour. No, this genus includes plants for all seasons and all reasons; foliage, flower, autumn colour, scent, groundcover, shrub or small tree, evergreen or deciduous, it's all there among the 120-odd species and the many hybrids and cultivars. Indeed, they're so variable that it would be quite possible to have an interesting garden of viburnums alone.
Although viburnums can be found over much of the temperate northern hemisphere and even South America, most of the common plants in our gardens, with the exceptions of the Laurustinus (Viburnum tinus) and the Guelder Rose (Viburnum opulus), occur naturally in temperate Asia or are derived from the species of that area.
About the only drawback with viburnums is that because they are so adaptable and easy to grow, they seem to have suffered from the 'familiarity breeds contempt' syndrome that sees common plants, however attractive and useful, relegated to the lower divisions of the garden league in favour of something more 'exciting'. Well, don't fall into that trap
