Last day of January.  Though it is cold and dark, you can experience Spring in Bergianska Trädgården, Bergius Botanic Garden. Every Sunday for only SEK 60 you can join a guided tour in the greenhouse and learn more  about the plants and flowers in blossom. A cup of coffee or tea with an eco-sandwich or cake in the café overlooking the greenshouse will add en extra ambiance to your visit.
