Viburnums are queens of the winter garden, bursting into flower in December and continuing the show right through till spring. Most are beautifully scented, with berries to follow the flowers; and many are evergreen too, giving you interest right around the year. One of the best is evergreen V. tinus, covered in pretty white blossom like snow; or there’s V.x bodnantense‘Dawn’ with clusters of flowers in palest pink with an intensely sweet scent. Pick a branch to bring into the house and it’ll perfume every room. All are easy to grow in sun or part shade, and in any soil – making them a must-have for every garden.
