Snowdrops in literature and other media
In Neil Gaiman's novel Stardust, Dunstan Thorn and subsequently his son Tristran carry a glass snowdrop that chimes when held. The flower has a very small, but pivotal role in the story
In the anime film Twelve Months (Sekai meisaku dowa mori wa ikiteiru in Japan), a greedy queen decrees that a basket of gold coins shall be rewarded to anyone who can bring her galanthus flowers in the dead of winter. A young girl named Anya is sent out during a snow storm by her cruel stepmother and find the spirits of the 12 months of the year, who take pity on her and not only save her from freezing to death, but make it possible for her to gather the flowers even in winter
In the manga "Snow Drop" by Choi kyung-ah, Snow Drop was the name of the book that Yo So-Na's mom wrote. The name of the four characters in the manga was taken from that book: So-na, Hae-gi, Ko-mo, Gae-Ri. In this manga, snowdrop represented hope and warmth, because of the legend it carries in Korea
Snowdrops feature in Seamus Heaney's poem Mid-term Break in the context of mourning a dead infant[13]
