Galanthus February and White ladies (see Symbols). Snowdrops are hardy herbaceous plants that perennate by underground bulbs. They are among the earliest spring bulbs to bloom, although a few forms of "G. nivalis" are autumn flowering. In colder climates, they will emerge through snow (see illustration). They naturalise relatively easily forming large drifts. These are often sterile, found near human habitation, and also former monastic sites. The leaves die back a few weeks after the flowers have faded. "Galanthus" plants are relatively vigorous and may spread rapidly by forming bulb offsets. They also spread by dispersal of seed, animals disturbing bulbs,
