Scape erect in flower, prostrate in fruit, green, solid. Inflorescences pendulous, 1-flowered, spathaceous; spathe bracteate, membranous; bracts 2, connate, split on 1 side. Flowers nodding, fragrant; perianath 2.5 cm or shorter; tepals 6, distinct, unequal; outer tepals spreading, white, narrowly obovate to almost orbicular, larger than inner; inner tepals overlapping, appearing tubular, green-spotted at apex only or apex and base, straight to semiorbicular, apex notched; stamens 6, inserted at bases of tepals, distinct; anthers basifixed, longer than filaments, bases lobed, apices tapered, dehiscense introrse, via terminal slits; ovary inferior, green, 3-locular, globose, septal nectaries present; style, white, unbranched, filiform; stigma indistinct to minutely capitate; pedicel wiry, short, slender. Fruits capsular, green, globose, fleshy, dehiscence loculicidal. Seeds 18–36, light brown, 3.5 mm, oblong to obtuse, elaiosomes fleshy. x = 12.

A number of Galanthus species, especially G. nivalis, are commonly cultivated for their late- winter and early-spring flowers, which emerge through the snow. Species of Galanthus are sometimes confused with Leucojum, snowflakes, a spring-flowering relative. The plants of Leucojum are usually taller, bear 2–3 flowers per stem, and their tepals are all equal.
