The marriage of struggling Wiesbaden ballad singer Willy Forster and seamstress Therese is plagued with constant financial difficulties.

Fifteen years later, Willy, who now has an international career as a singer under his stage name, 'Bill Perry', returns to Wiesbaden as part of a European tour.

In this film, pre-war German actors such as Willy Fritsch, Paul Klinger, Magda Schneider and Hertha Feiler appear alongside the children of other stars of that earlier era.

Romy Schneider, the daughter of Magda Schneider and the Austrian actor, Wolf Albach-Retty,[2] appears in her first film role together with Nina von Porembsky, the daughter of Alexa von Porembsky, as well as Götz George, the son of Heinrich George and Berta Drews.

Made in and around Wiesbaden, Wenn der weiße Flieder wieder blüht is one of the few so-called Heimatfilm pictures to have been set in the Hesse region as they were usually shot in the Alps, the Black Forest, or the Lüneburg Heath.
