More than 100,000 visitors are expected in Merseyside for the start of the Southport Flower show.
Gardening demonstrations will be held by more than 100 exhibitors
Antiques expert and Bargain Hunt TV star David Dickinson opened the 34-acre show on Thursday at the resort's Victoria Park.
The organisers say Southport is the country's largest independent flower, gardening and horticultural show.
The theme of the show, which runs until Sunday, is travel. More than 28 show gardens are competing for prizes.
Gardening demonstrations will be held by more than 100 exhibitors.
A huge floral display featuring one million blooms forms the largest of four centrepiece attractions in the arena.
Vegetable, herb and specialist plant displays will also be held alongside trade stands, displays of arts and crafts, specialist nurseries, gardening gadgets and accessories and sculptures.
Celebrity guests, including David Bellamy and celebrity gardener Roddy Llewellyn, are also due to make appearances over the four days.
The Southport Flower Show, originally staged by the local council, began in 1924.
