2021 Botany For Change Award – Winning Project

In November 2020, Klorane Botanical Foundation launched a call for projects among botany, horticulture, architecture and landscaping students for them to design the urban garden of tomorrow in a truly unique setting, Happy Vallée!

The purpose of this nationwide competition was to put plants back at the heart of our cities and, more specifically, to revegetate a 1,000m2 plot of land in 2021 near the A1 motorway in Roissy-en-France.



For almost 4 months, students worked on their ideas and 6 highly promising and creative projects were put to a professional judging panel made up of:

  • Gad Weil (Artistic Director, Happy Vallée),
  • Alain Baraton (Head Gardener at the Palace of Versailles),
  • Eric Chiron (Floral Designer and Gardener),
  • Nicolas Delporte (Landscape Designer – 2018 winner),
  • The city of Roissy-en-France represented by Patrick Pamart, Denis Côme and Rodolphe Meunier,
  • Klorane Botanical Foundation, represented by Stéphanie Lambey and Nawal Saïchi.

On 18 March, after some hours of deliberation, the panel shortlisted two finalists, the ‘Nature in Cultures’ Garden (Jardin ‘Nature en Cultures’) and the ‘Two Loops’ Garden (Jardin ‘Des Deux Boucles’), which were then put to the Klorane Botanical Foundation’s Instagram and Facebook communities and the residents of Roissy-en-France to choose the winning project.

And the winner is... the ‘Two Loops’ Garden

Following a public vote, the ‘Two Loops’ Garden project won over the most hearts and minds with 2,005 votes.


This 1,000m2 garden is built around a double loop: the northern part and the southern part.

The northern part will include the ‘Garden For All’, awakening visitors’ senses with real growing fruit to the delight of every nature-loving park goer. A natural hedge will provide a visual aspect that changes with the seasons.

The southern part will consist of a flowery meadow, flower beds and a ‘young shoots patch’, the latter designed as a colourful space to educate both young and old alike about the importance of biodiversity preservation.

The winning team 


The winning team for the 2021 edition of the Botany For Change Award is made up of 5 fourth-year landscape engineering students from Agrocampus Ouest in Angers.
Élise Brillaud, Suzanne Capillaire, Hugo Faure, Aurélien Mondon and Raphaël Perez won over the judging panel and the general public by coming up with a garden that highlights the rich biodiversity present in Île-de-France, in order to protect and enhance it, while putting local plant life firmly at the heart of their design.


The ‘Two Loops’ Garden will be unveiled and open to the public from 16 June 2021

The competition will continue in May for our 5 winning students. Klorane Botanical Foundation will fund the installation of the garden with support from the city of Roissy-en-France so they can dig, plant, structure and breathe life into their ideas.  Several weeks of work are planned for the plot of land in question.
The €5,000 prize will be handed over and the urban garden officially opened on 16 June in the presence of all partners in this initiative, including Roissy-en-France City Hall and the Happy Vallée Association.

The garden will then be open to the general public for everyone to enjoy. See you on 16 June for the grand unveiling!
