Snowdrop

The Common Snowdrop, Galanthus nivalis, is the best-known representative of a small genus in the family Liliaceae.

All species of Galanthus have bulbs, linear leaves, and erect flowering stalks, destitute of leaves but bearing at the top a solitary pendulous bell-shaped flower. This species grows 15cm tall, flowering in January or February in the northern temperate zone. The white flower has six petals, the outer three segments being larger and more convex than the inner series. The six anthers open by pores or short slits. The ovary is three-celled, ripening into a three-celled capsule. (Snowdrops should not be confused with their relatives Snowflakes, Leucojum species; Leucojums are much larger and flower in summer, with all six petals in the flower the same size.)

Propagation is by offsets removed when the plants are at rest, immediately after the leaves have withered; or by seeds sown either when ripe, or in spring. There are numerous cultivated varieties, different in the size of the flower and the period of flowering; the double form is probably the least attractive.

Other notable species:

• the Crimean snowdrop, G. plicatus, 30 cm tall, flowering January/February, white flowers, with broad leaves folded like a fan
• G. elwesii, a native of the Levant, 23 cm tall, Flowering January/February, with large flowers, the three inner segments of which have a much larger and more conspicuous green blotch than the more common kinds. All the species are very graceful, and as universal favourites amply repay cultivation.
