SNOWDROPS :

Galanthus (Snowdrop; Greek gála “milk”, ánthos “flower”) is a small genus of about 20 species of bulbous herbaceous plants in the Amaryllis family. Most flower in winter, before the vernal equinox (21 March in the Northern Hemisphere), but certain species flower in early spring and late autumn.
Snowdrops are sometimes confused with their relatives, snowflakes, which are Leucojum and Acis species; see below.
