Prince Charles and the Duchess of Cornwall will be joining show-goers amid the colourful sprawl of marquees, gardens and stalls which fill the park on Wednesday, July 27.
One of the centrepieces of this year's show will be a display created by Adnams Brewery and garden centre chain Notcutts, in association with the EDP.
Emma Hibbert from Adnams said the Happy and Glorious pub garden
Our garden was inspired by the many celebrations for the Queen's 90th birthday.
'The garden party and British pub are two quintessentially British traditions and we have brought them together at Sandringham Flower Show,' she said.
'The pub is so often at the hub of its community and the place where people join together for a variety of occasions. What better way to show glory and splendour than through the beauty of flowers and gardens in a pub setting where the public can celebrate with friends and family.
'This garden combines the expertise of two East Anglian family businesses; Adnams and Notcutts. From supplying plants to the Royal Household to creating commemorative beers, both companies have a passion for all things Royal.'
Many of the region's leading nurseries and horticultural specialists will be displaying their wares, while top gardeners compete for the coveted EDP Best In Show trophy in the show gardens competition.
There will also be more than 200 trade stands and stalls, catering for every aspect of gardening and outdoor living, along with refreshments, craft and horticultural talks marquees.
Main arena events include the Red Devils parachute display team, Atkinson Action Horses, RAF Halton Pipes and Drums, Portsmouth Action Field Gun Teams and Parkour Generations.
More than 20,000 attended last year's show. Since 1977, the event has donated more than £500,000 to charity.
Gates open at 9am. Admission is £10 adult, under-16s free. Ticket price includes admission to Sandringham Church, Sandringham Museum and gardens. Parking is free.
