Fields of 'May snow' appear in Swiss meadows

STORY: Locals refer to the flowers as 'May snow' since they create the appearance of fallen snow from a distance. The flowers have been a tourist attraction since the 19th century when floral parades were once organised with music and dancing.

Factors such as overgrazing and urbanisation have caused them to decline significantly.

A website guides tourists to trails overlooking Lake Geneva where narcissi fields can still be found.

Panels along the paths urge people to take just one handful per person from public fields.
