As the days grow shorter and Halloween marks the end of harvest and the beginning of winter, we explore the mysterious, the nocturnal, and the beautifully eerie corners of nature. Ecologist and bat expert Greg Slack joins us to uncover the secrets of these misunderstood night flyers — essential to our ecosystems but increasingly under threat. Then, houseplant expert and author Jane Perrone takes us on a chilling journey through the world’s most intoxicating and poisonous plants, revealing the strange allure of nature’s most dangerous creations. And finally, we turn toward the light again. RHS Garden Rosemoor’s Emma McFarline shares how she’s preparing her cottage garden for the seasons ahead, proving that even in the darkest months, there’s always something growing just beneath the surface.
