Plants – tireless, silent workers 

After many years of research and collaboration between scientists at the Botanical Garden and those at the Institut de recherche en biologie végétale (IRBV), the Montréal Space for Life Foundation has joined with the city of Montréal to fund a new Pathway to Phytotechnologies at the Botanical Garden. Starting in 2018, thousands of live plants will begin working silently to demonstrate their abilities in terms of rehabilitation, decontamination, soundproofing, filtration, stabilization, runoff control and air and water purification.

Seven stations seamlessly integrated into the heart of the Botanical Garden

From 2018 to 2023, the seven stations in this huge natural testing ground will open in succession, each showcasing phytotechnologies and their revolutionary ecological multitasking. Over the years, these bold green solutions will help to preserve biodiversity at the Botanical Garden, improve air, water and soil quality and protect various natural sites. 

Phytotechnologies: sustainable and esthetic environmental solutions 

The stations on the Pathway to Phytotechnologies will treat rainwater runoff and wastewater, help reduce the heat island effect in the Garden’s parking lot, stabilize the banks around the ponds and control invasive plants. They will also demonstrate how to mitigate the impact of urban noise and decontaminate soil.

Discoveries and inspiration for visitors 

All along the Pathway, visitors will learn about plants’ invisible powers and see how they help generate all kinds of environmental benefits efficiently, inexpensively and esthetically. The different types of phytotechnology will be explained through demonstrations, visitor activities and models, inspiring visitors to make connections with their own lives and imagine how these technologies could be used at home, in the workplace and in the community. 

Nature will be busy between now and 2023!

The seven stations on the Pathway to Phytotechnologies will be rolled out between 2018 and 2023.

  • 2018 - Filtering marshes

    Plants at this station will purify the water circulating in the different aquatic plant basins. 

  • 2019 - Living plant wall

    This ecosystem will clean the air, increase humidity levels, serve as a sound barrier and provide shelter for birds and insects.

  • 2019 - Decontamination 

    The soil above a former landfill will be used to create a demonstration zone looking at the use of phytoremediation to decontaminate soil.

  • 2020 - Controlling invasive plants

    The pond at the Frédéric Back Tree Pavilion is badly affected by invasive plants and will be used to illustrate various rehabilitation techniques.

  • 2021 -  Filtering marshes and green roof

    At the Youth Gardens, a new building with washrooms and a green roof will be added, and its greywater will be treated by means of filtering marshes.

  • 2021 - Stabilizing pond banks 

    Plants will be used to stabilize the banks and limit the spread of invasive plants in and around the ponds.  

  • 2023 - Cold islands

    A number of water retention zones will be created in the parking lot, and equipped with a green filtration system for better rainwater management and to reduce the heat-island effect.
