White ‘Lilies’ A Shrine to Madeleine

When I first read this in the media, something immediately struck me as very odd, something which made me ask myself, questions.

Lilies are very much a British thing, particularly white lilies and they are much associated with death and Funerals in the United Kingdom. Therefore something which most British people would be familiar with.

I have now had it confirmed by Portuguese sources, that Carnations and Roses are much more widely associated with death and Funerals in Portugal, not Lilies.

I am guessing Lilies are not that easy to obtain in Portugal, as say Roses or Carnations are. 

My theory is, that it’s was a British person or persons who created this shrine.

In view of the fact that the media have just started to carry this story, why have the person or persons who created this shrine, not made themselves known to anyone?
