I am almost sure it is a campion, but don't know its real name.
It is a nocturnal wild flower.

Scientific or popular will do.
But this is not a diurnal flower.
I have the impression that it is a nocturnal campion, but not sure, sure...
Is it a Silene [campion], but what variety?
I've looked everywhere on Google, but no final answer so far.

By real name do you mean Latin? Silene alba and Silene armeria (white and pink respectively).
