"Die Lotosblume", or "The Lotus-Flower", is a poem written by Heinrich Heine which was put to music by Robert Schumann in 1840. This Lied is part of Schumann's Myrthen collection (op. 25 no. 7)) and Six Song for Männerchor (op. 33 no. 3). The piece speaks of the blooming of a lotus flower and how it comes to life at night. Due to circumstances at the time, the lyrics were intended to have a double meaning.
