The international contest, which has seen a string of Horticulture Week award winners pick up prizes in recent years, is set to take place in the Netherlands.
The winner of this year's overall Grower of the Year Ornamentals award, which is selected from the winners of all the ornamental categories in the HW competition, will be put forward by awards event sponsor the NFU for the international contest.
The International Association of Horticultural Producers and FloraCulture International will sponsor the winner to attend the international contest in September.
Last year saw Majestic Trees pick up the silver medal in China and Hillier Nurseries won a gold medal in 2010.
NFU horticulture board chairman Sarah Pettitt said: "It is really exciting that the NFU is able to put the winner of Grower of the Year Ornamentals forward for the international competition. It's a great opportunity for British growers."
The Grower of the Year Awards will take place on 23 February in London. See www.groweroftheyear.co.uk.
