The RHS exceeded 10,000 visitors at this year's three-day Hyde Hall Flower Show and may open for an extra day next year.
Garden curator Ian Le Gros said 1,400 people came through the gate in the first hour of the event's opening day on Friday 3 August. The normal attendance was between 400 and 500 and by the close of the show, on Sunday 5 August, 11,200 people had visited.
Hyde Hall Flower Show drew 7,500 visitors in its first year - two years ago - and 9,500 last year. The first year's show was a loss-maker because of setting-up infrastructure costs, but "we are making things pay for themselves", said Le Gros.
"People want to be part of an experience in lovely rural Essex that is rising in profile. Our breakfast preview was well attended and last year we attracted visitors from the Midlands and further still, from Switzerland. Word is spreading and that's great."
Le Gros said Hyde Hall may follow Wisley's lead, which has gone for an extra, fifth, day. Next year, the show in Essex may go from three to four days. Around 50 exhibitors and trade stands at this year's event included Amulee Exotics, Bentley Plants, Madonna Nursery, Rose Cottage Plants, Darlac, Pepe Garden Furniture and John Harris Products.
Also attending Hyde Hall Flower Show was the South Essex (Basildon) Youth Offending Team. It presented a floral display called "Like us Every Pot is Different", reflecting wider society's diversity of backgrounds.
