Schachblumenfest Hetlingen

A Threatened Beauty Blooms in the Elbmarsch

The snake's head fritillary (Fritillaria meleagris) is one of the most unusual flowers in the North German flora—a delicate lily with hanging bell-shaped flowers, whose violet petals feature a characteristic checkerboard pattern. White variants are rarely found. In Germany, the species is considered highly endangered—its main distribution area is in moist meadows along riverbanks, and the Elbmarsch near Hetlingen offers precisely these conditions.

One of Germany's Largest Populations

The snake's head fritillary meadows in front of the old dike in Hetlingen host one of the largest and most significant populations of this endangered species in Germany. Thousands of blooms turn the marshland violet in April—a natural spectacle rarely experienced with such density anywhere in Germany.

When Exactly Do the Snake's Head Fritillaries Bloom?

The blooming period is weather-dependent. In past years, the peak bloom has occurred in the second half of April. The exact festival date is set annually at short notice—often only two weeks before the event, depending on when the main bloom begins. Registration via the Elbmarschenhaus Haseldorf.

In the Pinneberg District

Hetlingen is located in the Pinneberg district on the Lower Elbe, about 30 km northwest of Hamburg. The Schachblumenfest is an initiative of the Integrierten Station Unterelbe (ISU), the Elbmarschenhaus Haseldorf, and the NABU — a nature conservation festival that equally combines nature protection, nature experience, and regional identity.
