In applanate vernation the two leaf blades are pressed flat to each other within the bud and as they emerge; explicative leaves are also pressed flat against each other, but the edges of the leaves are folded back (externally recurved) or sometimes rolled; in supervolute plants, one leaf is tightly clasped around the other within the bud and generally remains at the point where the leaves emerge from the soil (for illustration, see Stearn and Davis). In the past, this feature has been used to distinguish between species and to determine the parentage of hybrids, but now has been shown to be homoplasious, and not useful in this regard.

''Leucojum'' species are much larger and flower in spring (or early summer, depending on the species), with all six

He merged ''Nivalis'' and ''Plicati'' into series ''Galanthus'', and divided ''Latifolii'' into two subseries, ''Glaucaefolii'' (Kem.-Nath) A.P.Davis and ''Viridifolii'' (Kem.-Nath) A.P.Davis.

Ecology

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, and water if disturbed by floods.

Snowdrop gardens

Celebrated as a sign of spring, snowdrops may form impressive carpets of white in areas where they are native or have been naturalised. These displays may attract large numbers of sightseers. There are a number of snowdrop gardens in England, Wales, Scotland, and Ireland. Several gardens open specially in February for visitors to admire the flowers. Sixty gardens took part in Scotland's first Snowdrop Festival (1 Feb–11 March 2007). Several gardens in England open during snowdrop season for the

Cultivars

Numerous single- and double-flowered cultivars of ''Galanthus nivalis'' are known, and also of several other ''Galanthus'' species, particularly ''G. plicatus'' and ''G. elwesii''. Also, many hybrids between these and other species exist (more than 500 cultivars are described in Bishop, Davis, and Grimshaw's book, plus lists of many cultivars that have now been lost, and others not seen by the authors). They differ particularly in the size, shape, and markings of the flower, the period of flowering, and other characteristics, mainly of interest to the keen (even fanatical) snowdrop collectors, known as " galanthophiles", who hold meetings where the scarcer cultivars change hands.  Double-flowered cultivars and forms, such as the extremely common ''Galanthus nivalis'' f. ''pleniflorus'' 'Flore Pleno', may be less attractive to some people, but they can have greater visual impact in a garden setting. Cultivars with yellow markings and ovaries rather than the usual green are also grown, such as 'Wendy's Gold'. Many hybrids have also occurred in cultivation.
