Passengers flying from Terminal 3 at Heathrow Airport are the first to be treated to a "Garden Gate" before they fly.
The hundreds and thousands of people boarding from Gate 25 will be privy to a green oasis designed to spread a sense of calm and relaxation before take off.
The iconic living wall is made up of a phenomenal 1,680 plants including the English native Ivy and Peace Lily, which has been installed by Biotecture and is on trial for six months.
If the trial is a success, Heathrow will consider introducing Garden Gates across the airport.
Emma Gilthorpe, Heathrow's strategy director, said: "With our new Garden Gate, our passengers can enjoy a natural sanctuary of rest and relaxation as they make their way through the airport, with 1,680 plants ready to see them on their way.”
The Garden Gate is in response to improving passengers' journeys, having recently received its best ever passenger service scores this summer.
There are seven garden walls each containing 240 plants in the gate room.
Each plant panel is fitted with a water reservoir and nutrient system so the plants can grow in an artificial environment.
On average, 287,000 passengers go through Gate 25, Terminal 3, every year.
Last month, Heathrow Airport built a giant world map at Terminal 5 out of 2,000 fresh flowers , to celebrate a new season of fragrances.

Richard Sabin, director of Biotecture, added: “The Garden Gate at Heathrow is the latest, and perhaps most iconic, living wall representing the advancement of eco-technologies in the UK.
"The world’s major cities are increasingly investing in green infrastructure, and the Garden Gate, both technically and ecologically, is cutting edge for its ease of installation, unique plant selection and LED lighting system.
"As the nexus of transit and technology, transportation hubs are ideal locations for green infrastructure to become an investment in public health and wellbeing.”
Other locations in the UK to adopt green Biotecture sites include the Walkie Talkie building, Edgware Road, Elephant and Castle tube station and MTV HQ in London.
