Science EN ↓ 5 episodes

Sharing the stories of growers, collectors, and the plants they cherish. Keepers of the Green tells the stories behind the plants people can't stop thinking about — the collectors who've spent decades hunting a single species, the windowsill growers whose succulents have become family, the hybridisers creating something the world has never seen. We go beyond care tips to explore obsession, craft, and the unexpected ways plants shape our lives. Whether you're new to growing or knee-deep in rare specimens, these are the stories that keep our green world alive.
