Four leading florists have created installations that transform areas of London restaurant Sketch into blooming gardens or woodland glades, to coincide with this week's Chelsea Flower Show (+ slideshow).

The Mayfair restaurant invited the florists to develop bold installations that showcase their skills at the event, which Sketch has labelled the Mayfair Flower Show in reference to the famous horticultural show taking place concurrently in Chelsea.

Each installation celebrates the British countryside, so only plants found in the UK were used, including birch, roses, foxgloves and lily of the valley.

"This flower show is what Sketch is about; bringing together creative minds with different styles under the same roof," the restaurant's founder and owner Mourad Mazouz told Dezeen.

"The project fits perfectly with how Sketch is often described, an Alice in Wonderland journey as you wander from room to room, and in this case from garden to garden."

The entrance to the building, which was designed by James Wyatt in 1779, is filled with plants and foliage by The Flower Appreciation Society. This creates a wild and verdant passage leading to the reception area.

By Appointment Only was influenced by the romantic style of Victorian art when decorating a staircase with roses and various other flowers that create a bright arrangement resembling the palette of Impressionist painters.

The staircase descends towards the restaurant's Gallery dining room, which features walls lined with sketches by British artist David Shrigley, who previously designed a ceramic tea service for serving afternoon tea at the restaurant.

Shrigley is the second artist invited to decorate the interior of the Gallery, after Martin Creed filled the space with eclectic vintage furniture and added zigzagging marble floor tiles and graphic patterns to the walls.

In the Champagne Pommery Lounge, housed in Sketch's Glade cocktail area, London florist JamJar attached hundreds of blooms to a suspended mesh to create an intensely colourful floral canopy that complements the painted woodland murals covering the walls.

Carly Rogers Flowers transformed an area at the top of the stairs leading to the space housing the restaurant's unusual pod-shaped toilets into a woodland garden.

A carpet of moss covers a domed surface, providing a base for a tree stump, plants, grasses, trees and flowers including foxgloves.

"I feel all four installations work independently and are so magical that you forget the space they're in," Mazouz added.

"At the same time, the gardens only exist because of the room they are in. If you think with this project that each room is a landscape, the installations by all four florists explore their relationship with the building."

Alongside the event, the restaurant is offering a floral-inspired lunch menu featuring flowers in all three courses, a floral afternoon tea, and a specially devised cocktail made using rose liqueur. The installations will remain in place until 29 May.
