Fern flower

The fern flower is a magic flower in Slavic mythology (Belarusian: папараць-кветка, Polish: kwiat paproci, Russian: цветок папоротника, Ukrainian: цвіт-папороть), in Baltic mythology (Lithuanian: paparčio žiedas, Latvian: papardes zieds) and in Estonian mythology (Estonian: sõnajalaõis).

According to the myth, this flower blooms for a very short time on the eve of the Summer solstice (celebrated on June 21 or sometimes July 7) The flower brings fortune to the person who finds it. In various versions of the tale, the fern flower brings luck, wealth, or the ability to understand animal speech. However, the flower is closely guarded by evil spirits and anyone who finds the flower will have access to earthly riches, which have never benefited anyone, so the decision to pick the flower or leave it alone is left up to the individual.

In the Estonian, Lithuanian and Latvian tradition, the fern flower is supposed to appear only on the night of 23 to 24 June during the celebration of the summer solstice which is called Jāņi in Latvia, Joninės or Rasos in Lithuania, Jaaniõhtu or Jaaniöö in Estonia and juhannus in Finland. The celebration has pre-Christian origins. In addition to the idea that the finder of the fern flower will become rich or happy, here, the fern flower is sometimes perceived a symbol of fertility. During this supposedly magical night, young couples go into the woods "seeking the fern flower", which is most commonly read as a euphemism for sex. Sex can lead to pregnancy; the child could be thought of as the fern flower.
