Lily flower
Lillien is a rare variant of Lillian, which is derived from the Latin word 'lilium' referring to the lily flower. Historically, the lily has served as a symbol of purity, innocence, and rebirth. While the 'Lillian' spelling has been a staple of English naming for centuries, the 'Lillien' spelling offers a more unique, modern aesthetic.
