Denmark
Despite the fact that Valentine's Day is a relatively new holiday in Denmark (celebrated since the early 1990s, according to the Danish Ministry of Foreign Affairs), the country has embraced February 14th with a Danish twist. Instead of roses, friends and lovers present pressed white flowers known as snowdrops.
Another famous Valentine's Day tradition in Denmark is the exchange of "lover's cards." While lover's cards were traditionally translucent cards depicting the card presenter offering a gift to his girlfriend, the phrase is now used to refer to any card shared on Valentine's Day.
On February 14th, men also give women gaekkebrev, a "joking letter" consisting of a funny poem or rhyme written on intricately cut paper and signed only with anonymous dots. If a woman who receives the gaekkebrev can correctly guess the sender, she earns herself an Easter egg later that year.
