Shoots of spring flowers are pushing out of the soil in England and in the even-warmer climes of the Channel Islands primroses and dog violets are blooming.
Botany experts say it is likely that lilac and apple trees will be blossoming next month.
Tony Kirkham, head of the arboretum at Kew Gardens, southwest London, said: "This kind of weather is very confusing for plants. Some trees will blossom as a last-minute fling before the winter and some flowers come up because they are getting such mixed messages from the weather. It makes it look like spring has come early." ...
Last year, gardeners reported a "phantom spring" in early November. Reports on a BBC website included red admiral butterflies, trees in blossom and flowering violets. Meteorologists say that the warming climate means the phenomenon is likely to become common.
