The plants were supplied by Rentahedge, the group behind previous installations in the Westfield shopping centre and Tavistock Square.
More than 260m of predominantly Laurel hedge was supplied to help remind tourists they should leave the beaten track and explore the capital’s famous commercial district.
An array of entertainments awaited visitors to the heard of the maze, highlighting the range on offer in the West End.
Rentahedge manager John Harca said: "We grow the plants and we supply them. The West End Partnership – a business association for the area – wanted to promote theatre land to show tourists the West End is like a maze."
The maze itself measures approximately 30m x 20m and each hedge is 2.4m high. It was constructed using 118 individual 2m sections, with a mixture of laurel and thuja hedging.
Six articulated lorries delivered the hedging to Trafalgar Square and a dedicated team worked through the night, taking approximately six hours, to build the maze structure.
Rentahedge has been supplying instant hedges for functions and events for the last five years and Harca said it was a growing market.
Their sister company Instahedge also supplies hedging products via the internet.
