The Valentine's Day bouquet — the gift that every woman in Britain will be waiting for next week — has become the latest bête noire among environmental campaigners.
Latest Government figures show that the flowers that make up the average bunch have flown 33,800 miles to reach Britain.
In the past three years, the amount of flowers imported from the Netherlands has fallen by 47 per cent to 94,000 tons, while those from Africa have risen 39 per cent to 17,000 tons.
Environmentalists warned that "flower miles" could have serious implications on climate change in terms of carbon dioxide emissions from aeroplanes.
Andrew Sims, the policy director of the New Economics Foundation, said: "There are plenty of flowers that grow in Britain in the winter and don't need to be hothoused.
"Air freighting flowers half way round the world contributes to global warming.
"You can argue the planes would be flying anyway but the amount of greenhouse gases pumped out depends on the weight of the cargo."
