Die Lotosblume[1] ("The Lotus Flower") is a poem written by Heinrich Heine, and published in his Buch der Lieder (The Book of Songs, 1827).
[5] The piece speaks of the blooming of a lotus flower, who hides from the sun and only reveals herself at night to her lover, the moon.
Schuman's love for Clara is tender and passionate, and allows her to blossom into her full potential like the lotusblume flower blooms at night.
