The two-day event, held on 1 and 2 August, will include a professional exhibitors' marquee, featuring award winners from some of the country's biggest shows; the unveiling of Chorley's Chelsea exhibit, 'The Evaders' Garden'; celebrity gardeners Rachael de Thame and Bob Flowerdew; horticultural trade stands and an amateur marquee incorporating flower and pot plant classes and floral art.
Councillor Alistair Bradley, leader of Chorley Council, said: "We've built a brilliant reputation in Chorley for our floral displays and there is a real appetite for a show of this type as we build Chorley into one of the up-and-coming visitor destinations in the North West.
"We've worked carefully with horticultural organisations to ensure that the show focuses on the floral displays and gardening and it's an exciting new show set in a new location that will really make for a fantastic day out.
The showground is in Astley Park, the former location of the Royal Lancashire Show, with free parking on the day. Tickets are £4 for adults, £2 for children and £10 for families.
