Colman Getty has scooped the project brief, having handled PR for The RHS Hampton Court Palace Flower Show and RHS Flower Show Tatton Park for the past two years.
The move comes as part of an effort to allow RHS’ in-house team to focus on increasing awareness of the RHS’ charitable work and other national gardening spots including the Lindley Library in Westminster.
Dotti Irving, chief executive of Colman Getty, said that she would be part of a team of seven from the agency handling the brief, with numbers increasing in the final days before the show.
She said: 'We’re thrilled to be taking on the RHS Chelsea Flower Show and look forward to working with the in-house team and all the exhibitors to maintain it as one of the most famous strands of Brand Britain for 2012.'
She added that there were a number of PR initiatives set to be rolled out over the next few months to promote the show, which attracts more than 100 TV crews and 1,000 journalists.
Dan Wolfe, RHS director of communications, said: 'This is a terrific move for the RHS Chelsea Flower Show. We know that we can trust Colman Getty to deliver on the media and exhibitor front, allowing us to raise awareness of other RHS world class gardening initiatives, our charitable work and important gardening matters through the worldwide media focus on RHS Chelsea.'
