Galanthus is a genus of small, bulbous perennial plants.

These herbaceous plants belong to the family Amaryllidaceae. They are famous for being among the first flowers to bloom in late winter or early spring. Most species flower before the vernal equinox, which occurs on March 20 or 21 in the Northern Hemisphere. This timing allows them to take advantage of early sunlight. Because they grow from bulbs, they are able to survive cold temperatures.

The physical structure of a snowdrop is very specific. Each plant typically has two linear, strap-shaped leaves. These leaves emerge from a bulb and are initially wrapped in a protective sheath called cataphylls. A single flowering stalk, known as a scape, grows upright from the bulb. At the top of this scape, a pair of bract-like structures called spathes protects the developing flower. From these spathes, a single pendulous flower hangs downward on a slender stem called a pedicel.

The flower itself is composed of six petal-like segments called tepals. These tepals are arranged in two distinct circles, or whorls. The outer whorl contains three larger, spreading tepals. The inner whorl consists of three smaller tepals. These inner segments often feature green markings at their base or tips. These markings can sometimes appear as bridge-shaped patterns. The reproductive parts include six short stamens and a three-celled ovary. After pollination, this ovary matures into a fleshy, three-celled capsule fruit.

Botanists study how the leaves emerge from the bulb, a process called vernation. There are three main types of vernation in the Galanthus genus. In applanate vernation, the leaf blades are pressed flat against each other. In explicative vernation, the leaves are flat but their edges are folded back. In supervolute vernation, one leaf tightly clasps the other within the bud. While scientists once used these patterns to identify different species, modern research shows this trait can be unreliable. Today, scientists use molecular phylogenetics to define species more accurately.

History shows that humans have observed snowdrops for millennia. The Greek author Theophrastus described them in the fourth century BCE. He called them "white violets" and noted how they bloom during mild winters. In the 1500s, botanists like Rembert Dodoens and John Gerard provided early illustrations. However, the genus was not formally named Galanthus until 1753. This was done by Carl Linnaeus, who established Galanthus nivalis as the type species. Linnaeus is the person credited with the official botanical authority for the name.

Snowdrops have a wide natural distribution across Europe and Western Asia.

They range from the Pyrenees mountains in the west to Iran in the east. They are also found in the Caucasus, Turkey, and the Mediterranean. Some species are native to specific areas, such as Galanthus fosteri in Jordan and Syria. While many species prefer woodlands, some grow in grasslands or mountains. Some plants, like Galanthus nivalis, have become naturalized in North America. In the Russian Udmurt republic, they grow even above the 56th parallel.

New discoveries continue to expand our knowledge of this genus. For example, Galanthus trojanus was identified in Turkey in 2001. In 2012, researchers found Galanthus panjutinii in a small area of Georgia and Russia. Scientists also identified Galanthus samothracicus in Greece in 2014. These discoveries show that the genus is still being mapped by science. Interestingly, snowdrops have a unique way of spreading their seeds. The seeds possess a small appendage called an elaiosome. This structure contains substances that attract ants. Ants carry the seeds to new locations, helping the plants expand their reach.
