Asda is selling roses for Valentine's Day at just £2 for a dozen, or 16p a stem. Charities and environmental experts have raised concerns about the cut-price flowers, many of which come from Africa and particularly Kenya's Lake Naivasha region. University of Leicester ecologist Dr David Harper said, 'If you buy a T-shirt really cheaply, the chances are that it was child labour that made them. 'The same principle applies with flowers, you cannot get them cheap without a cost to the environment or people in a developing country.'
