Trees are everywhere in La Confluence. 4,500 will have been planted by the end of the works. To guarantee their longevity, particular care is taken in the selection of different species that are adapted to global warming and help promote biodiversity. They provide coolness and tranquillity in everyday life.


Plant life is essential in a sustainable city, and trees play a major role. They:

  • structure the space
  • break up the mineral character of the landscape,
  • capture carbon dioxide,
  • produce essential oxygen,
  • help facilitate rainwater infiltration.
  • cool the air in summer
  • promote biodiversity

The high number of trees in La Confluence is the fruit of meticulous planning. The species are chosen depending on their origin and ability to adapt to global warming.



On the upper quays of the banks of the Saône, some of the plane trees have been replaced. They were old, sick and lacked space. New species are now growing alongside the ones that were left. They are more conducive to biodiversity and were chosen for their ability to withstand heat and adapt to arid soil, for example Turkey oak, maple and linden. Along the lower quays, typical riverbank species have been chosen including black poplar, ash, alder and white willow. They are resistant to high river levels and provide a diverse habitat.

130 trees have already been planted around Station Mue, at the heart of the future Le Champ district. They include regional species as well as trees native to the South that are accustomed to hot, dry climates and adapted to global warming. This is the case of the European nettle tree and the Judas tree, for example. Dry and wet meadows add a finishing touch to create the feel of a leafy urban park.

La Confluence benefits from two vast green spaces:

  • Le Champ to the south, which is currently under development (6 hectares), 
  • the banks of the Saône running from north to south along the Lyon peninsula and which include Saône Park and the public spaces in the old Rambaud port. 

They contribute to quality of life in the quarter and offer a breath of fresh air. They limit the effect of temperature highs in summer and improve air quality.


Stretching out over 14 hectares, Saône Park bedecks the western side of La Confluence in green and blue. It is lined with gardens, play areas and sports amenities. The three water gardens, designed by landscapers Georges Descombes and ADR Architects, are particularly remarkable. The water gardens provide a unique symbiosis between greenery and water, and water and the city. They provide natural spaces, biodiversity reserves and facilitate rainwater infiltration. Respectively named Ouagadougou and Jean Couty, in tribute to the Lyon painter, they are planted with aquatic vegetation where swans, ducks and other insects thrive.
