Snowdrops

Snowdrops (now known as Nettledrops) are flowers found exclusively in the Kingdom of Freezenburg. They are known for being one of the only flowers that can bloom in the snow alongside the Ice Lily and the Edelweiss. 

Snowdrops were first created by the fairy, Miss Nettle. However in 'The Secret Library: Olaf and the Tale of Miss Nettle', it is revealed that the flowers were stolen from her by the Royal Gardener of Freezenburg. As such, the flower has been deeply immersed into the culture of the kingdom but without acknowledgement of Miss Nettle.

However Princess Sofia tells the King of Freezenburg (Princess Hildegard's Father) about Miss Nettle and he officially acknowledges her by renaming Snowdrops to 'Nettledrops'.
