Tens of thousands of people are expected to converge on Sandringham tomorrow for one of the most eagerly awaited events of Norfolk's summer calendar: the annual flower show.

The rolling parkland of the royal estate will come to life with wave after wave of people from across East Anglia and beyond piling in to enjoy the 130th show after the grounds open at 7.30am.

Prince Charles and the Duchess of Cornwall are due to attend the event and traditionally the royal couple have toured the show in an open-topped carriage before heading on a walkabout around the showground.

Top television gardeners Chris Beardshaw and Alan Mason will also have the unenviable task of judging the show gardens – and awarding the EDP Best in Show trophy. The gardeners will also be taking part in the popular Gardeners' Forum.

They will be joined by Martyn Davey, head of horticulture and design at Easton College, and radio gardener and allotment expert Terry Walton. The forum will culminate in a Gardeners' Questions event.

The specially-designed centrepiece of the Royal Marquee will be revealed for the first time as the royal visitors are the first to set eyes on the creation. The one-day show, in association with the EDP, also features leading horticultural specialists and nurseries from across the region.

In addition to the displays and show gardens, around 200 trade stands, craft marquee, main arena events, children's entertainment and a military band will all add to the unique atmosphere of the show.

The royal marquees contain the competitions for vegetables, fruit, flowers and floral art, with entries grown by local residents.

In the amateur's marquee, local gardening and horticultural clubs enter a display competition, while the horticultural trades marquee features displays by leading nurseries.

The art of flower arranging will also be demonstrated by Nick Cole, who runs Hunstanton-based florist Scent with Love.

Arena attractions include The Imps motorcycle display team, the Minden marching band, dog and duck displays and a sheep show.

The profits from every show have been donated to local charities and since 1977 some �450,000 has been distributed.

Don't forget to grab your EDP goody bag – each has a copy of the paper, pair of gardening gloves, packets of Suttons seeds, fruit, drink, crisps, sweets and costs �2. They will be available on the gates or from our stand on the showground.

The show will start at 9am and finish at 5pm. Admission is �8, under-16s free, and includes access to the church, the grounds and museum. Sandringham House is not open on show day.
