Under our feet, the ground harbors colossal biodiversity. It works in secret for our benefit. Facing drought, can it resist? In the first episode of this new summer series, biologist Marc-André Selosse gives a clear answer: yes, but... All plants need water to live. But some can withstand long periods of drought. With these 5 flowers, the chore of watering is over! The episode explores the hidden world of fungi and plants, revealing how some species have evolved to survive in extreme conditions. Selosse explains that while most plants require regular watering, certain types have developed unique adaptations to endure dry spells. These adaptations allow them to survive without frequent irrigation, making them ideal for gardens in regions affected by water scarcity. Selosse highlights five specific flowers that are particularly resilient. These plants have deep root systems or the ability to store water in their tissues, enabling them to thrive even when rainfall is scarce. By showcasing these species, the episode aims to educate viewers on sustainable gardening practices and the importance of biodiversity in maintaining ecological balance. The series promises to delve deeper into the fascinating relationships between plants, fungi, and the environment. Each episode will explore different aspects of this underground world, offering insights into how nature adapts to challenges like climate change and resource scarcity. This first episode sets the stage for a season that combines science with practical advice for gardeners and nature enthusiasts alike.
