After a series of intense heatwaves and prolonged droughts, many parks and gardens have suffered significant damage. In response to the growing challenges of climate change, gardeners and landscapers are exploring new plant species—some from different regions—that are better suited to withstand water shortages and extreme heat. This shift is necessary to ensure the survival of green spaces in the face of increasingly unpredictable weather patterns. Matthieu Picot, a landscaper based in Nantes, is one of many professionals adapting to these changes. In his projects, he is incorporating plant species that are more resilient to the local climate, even if they are not originally from the region. "We have to allow non-native species to take root because otherwise, we risk losing all the local, endemic species that we currently rely on," he explains. While not all exotic species may be suitable, those that can provide shade and coolness are worth considering. Picot emphasizes that nature has its own adaptive strategies, and by observing it, we can learn to better manage our landscapes. New plant species are often more adaptable to local soils and climates than traditional ones. Picot notes that certain native plants are no longer as resilient, and this has led to the emergence of "super weeds" that continue to thrive even in harsh conditions. He believes that rather than resisting these changes, it is better to let nature guide the way. However, this approach also means rethinking the traditional French landscape, which has historically been shaped by a specific climate and cultural context. As the climate changes and societal needs evolve, so too must our understanding of how nature can adapt. In Saint-Sébastien-sur-Loire, the effects of the recent heat are visible—yellowed grass and scorched leaves in local parks. Aymeric Mottier, the city's director of public spaces, acknowledges the challenges but highlights the importance of choosing the right species. For example, a cork oak, a xerophytic plant that thrives in dry conditions, was planted in clay soil. While it struggled with the winter conditions, it demonstrates the complexity of adapting to climate change. Mottier explains that while drought-resistant species are necessary, they must be chosen carefully to match local soil and climate conditions rather than simply creating a Mediterranean-style forest. Gardeners in Saint-Sébastien-sur-Loire face an extreme climate, with winters as cold as -5°C and summers reaching up to 43°C. Mottier describes 2026 as an exceptional year, noting that even long-time gardeners have never seen such severe plant decline. While humans and animals can find ways to cope, plants often struggle under these conditions. For now, there is no single solution—only continuous experimentation and observation. Mottier offers a simple tip for assessing whether trees have survived: if a branch is still flexible, the tree is likely still alive. Some trees may have gone into a protective state, shedding their leaves, but they may not be dead yet.
