Chionodoxa (snow glory)
The bulbs naturalize readily by seeding themselves wherever they are left undisturbed. They prefer light shade and a woodsy soil that is well-drained but not too dry. Little maintenance is required but a mulch of decayed manure and leaf-mould in the autumn once every two years will insure more and finer flowers each spring. Lift and divide overcrowded bulbs in autumn. Plant 8cm deep, 8cm apart.
