Self-proclaimed "guardian of the daffodils" Kim "Dusty" Murtagh said all three daffodil fields would be on display for the first time for more than 50 years.
The Weatherstons attraction, on the outskirts of Lawrence, will open on Saturday, September 5, with the annual Daffodil Dayze Gala planned for Sunday, September 27.
The fields surround the ruins of the former Hart's Black Horse Brewery and Ms Murtagh said the attraction was opened every spring to inject some colour into the lives of everyone after winter and to raise money so restoration of the site could continue.
She and her team of showgirls dress up in costume to create an atmosphere of days past.
The prospects of a colourful start to spring in the area were looking good, she said.
"If you were impressed with the vista in previous years, you should see it now."
A new walking track leads from the main field up to the top field, coming down behind the brewery ruins before entering the area commonly referred to as "Narnia", complete with its own wardrobe, and back into the north field - a 1.5km circuit of colour.
Ms Murtagh said the gala day would feature guided tours of the fields, traditional food for sale and old-time music in the background to re-create the atmosphere of similar events more than 100 years ago.
