The Landscape Show is designed for landscape architects, garden designers, architects and florists and runs on 13-14 April 2011 at London Olympia. Celebrity speakers being lined up include Matthew Wilson, David Domoney and Andy Sturgeon.
Organisers Thirty Forty Nine event director Jeremy Storey-Walker said: "Interest has been phenomenal. There has never been anything like this in London. It's where the money is and where the architects and landscape gardeners are. This will be an all-encompassing trade show to find new suppliers."
Around 30 seminar topics such as planning legislation and plants that cure illnesses are being considered by speakers such as English Heritage.
The show will cater for 130 exhibitors. More than 30, including Clark and Spears, Europlanters, Nieuwkoop Europe and Koberg BV, have booked so far. Organisers expect up to 1,000 visitors a day. The show is a reinvention of Efig, formerly held in Peterborough.
