The most prestigious fixture in the horticultural calendar, the RHS Chelsea Flower Show runs from 22 to 26 May 2018. In the grounds of Sir Christopher Wren’s Royal Hospital Chelsea, more than 150,000 visitors will promenade around its Great Pavilion, which is big enough to hold 500 London buses. For the third time, this year the RHS is working with Raymond Blanc and Sodexo Prestige to enhance corporate hospitality at the show. For those wanting to access the Jardin Blanc, there’s a choice of five daytime and evening packages, starting from £225pp. The area’s QEII Suite is available for exclusive hire from £250pp.
