Here is a real winter wonder growing in the greenhouses at Bristol Botanic Garden. It is the Darwin orchid - Angraecum sesquipedale. It is famous because when Darwin found it the pollinating moth had not been identified
and he predicted it would have a long tongue to match and he was right so the moth has in its Latin name "praedicta" It is an example of co-evolution. It only flowers for a week every year and the spurs in this one are about ten inches long.
