"" (literally "A rose has sprung up") is a Christmas carol and Marian hymn of German origin. It is most commonly translated into English as "Lo, how a rose e'er blooming" and is also called "A Spotless Rose" and "Behold a Rose of Judah". The rose in the German text is a symbolic reference to the Virgin Mary. The hymn makes reference to the Old Testament prophecies of Isaiah, which in Christian interpretation foretell the Incarnation of Christ, and to the Tree of Jesse, a traditional symbol of the lineage of Jesus.

The German text affirms that Mary is a "pure maiden" ("die reine Magd"), emphasizing the doctrine of the Virgin birth of Jesus. In Theodore Baker's 1894 English translation, on the other hand, the second verse indicates that the rose symbolizes the infant Christ. Since the 19th century, other verses have been added, both in German and in translation.
