The Botanical Garden in Powsin has been hosting exhibitions of art inspired by nature for many years, including painting, drawing, artistic photography and sculpture. Temporary exhibitions are presented in the historic Janówek Villa (Wojciech Fangor's Manor House) and in the café hall.

For a quarter of a century, the Garden has been the venue for concerts as part of the International Piano Festival "Musical Floralia - Music in Flowers." The festival is organized in conjunction with the Frederic Chopin Society and is one of the oldest festivals in Poland. It is held every year from May to June every Sunday on the terrace of the Janówek villa and the surrounding glade that forms a natural amphitheater together with the tree canopy.

All expositions and concerts are available with admission tickets and year-round passes.
