I think the organic flower trend is very interesting - I appreciate that people care more and more about where the products they use actually come from. This can also be seen as many big companies that sell and deliver flowers in London (my hometown) and the area are starting to have a range of organic flowers in their portfolio.
However, I think there is a huge potential for fraud as already mentioned and I think even if people are saying they want "ethical flowers" they are often still not prepared to pay the higher price.
