The installation is part of a project initiated by SNCF Gares & Connexions, the SNCF subsidiary tasked with managing, operating and developing the 3,000 rail stations across France.
The "garden station" is the creation of landscape designer Alexis Tricoire.
Five trees surrounded by luminous rings, float five metres high across the glazed façade of the station.
In the forecourt of the station, two trees, also surrounded by luminous rings, are transformed into seats.
Each luminous ring, three metres in diameter and weighing one ton, is made of brushed stainless steel including light polycarbonate windows and three types of lighting that promote plant growth.
This design was developed by Tricoire for over a decade and includes irrigation and misting systems.
Angers has been named the greenest city of France.
The station, which has 15,000 passengers a day, is directly connected to Paris and Nantes.
