"pleniflorus" 'Flore Pleno', had appeared by 1703, when it was illustrated in "The Duchess of Beaufort's Book". It spread (and was spread) rapidly through northern Europe (by vegetative means, as it sets no seed).

There are
Galanthus nivalis (flowering stalk), which bears at the top a pair of bract-like spathe valves joined by a papery membrane. From between them emerges a solitary, pendulous, bell-shaped white flower, held on a slender pedicel. The flower consists of six tepals, also referred to as segments.

The inner surface has a faint green mark covering
