Grow the world's biggest Gigantomo Tomato and win up to £3,000

Gardeners lucky enough to get hold of 'Gigantomo'® plants or seeds in 2017 can take the fruits of their harvest to the Harrogate Autumn Flower Show (15-17 September 2017) and take part in the National Gigantomo® Championships. Thompson & Morgan is offering a top prize of £250 for the heaviest fruit, with a further £3,000 jackpot up for grabs if it also breaks the world record at the time of the show* (currently 7lb 12oz).

'Gigantomo'® can reach over 6ft tall, producing fruits up to 10 inches wide and 3lbs in weight, which can be harvested from mid-summer. It is available as both seeds and plants. The new disease-resistant variety is the result of almost two decades of research and development by breeders in the UK and the US. Simon Crawford, one of the UK's leading plant breeders, was called in five years ago to finish the work of late American grower Paul Thomas, who spent 15 years trying to breed the huge tomato.

The Harrogate Autumn Flower Show is staged at the Great Yorkshire Showground and hosts two large shows for pristine exhibition fruit and veg, as well as their less glamorous giant cousins. It is also home to Britain’s biggest exhibition by specialist gardening groups featuring over 5000 spectacular autumn blooms, plus show gardens and stunning plant nursery displays.

*Full details and schedules for the 2017 North of England Horticultural Society’s Fruit and Vegetable Show, including the giant veg classes, will be available from February. Visit
