The essential beauty of the snowdrop lies in the linear perfection of the single bell. Classically, they are planted in sweeping drifts beneath deciduous trees, demonstrating the awesome power of repetition. But they can also be used in stunning modern combinations. Of the 500 varieties of snowdrop (yes, really), Galanthus nivalis and Galanthus elwesii are the most common. They'll go with anything. Those with double bells need a bit more thought.
