Snowdrops are one of the most beautiful winter flowers you can buy for your garden. They naturalise, meaning they will spread in small clumps to create a wild effect, looking particularly impressive in hedgerow areas and as drifts in the grass. This variety has beautiful while single flowers. Just dig a small hole about 12 cm deep and pop the bulbs in. Then cover with soil and water. You can order ten, fifteen, twenty or twenty-five bulbs.
