Mega muscles are needed to lift this pumpkin that peers out at people passing the front window of Fabulous Flowers in Bridge Street, Abingdon.

But just how heavy is the whopper?

A prize is on offer for the person who guesses its weight or comes closest. Money raised will go to the Abingdon Alzheimer's Club.

The pumpkin was brought by Fabulous Flowers owners Matthew Taylor and Gary Cooper.

Mr Taylor said: "It is enormous and we've named it the Whopper. We decided to donate money from the competition to the Alzheimer's Club in the town because the husband of one of our customers suffers from the disease."

Entries cost £1 and the best guess wins prizes worth a total of £100 - a large bouquet, pink Champagne truffles and a flower-scented candles.

Once the weight has been announced, the pumpkin will be presented to Abingdon Hospital.

Mr Cooper said: "They can treat the patients to pumpkin pie and pumpkin soup."
