The famous flower clock in the Jardin Anglais in Geneva is protected by an alarm.
If anyone gets too close and starts to trample on the flowers – the alarm will sound, hopefully scaring them off.
But it’s been going off regularly recently – normally without anyone in sight.
Technicians believe the heavy rain with the sun means the plants are growing too quickly – which is triggering the alarm.
Further research is being undertaken, but some plants could be replaced, which would be a relief to local residents.
