As 2025 comes to a close, host Nick Turrell looks back on a year of discovery in this special end-of-year edition of Gardening with the RHS. From the quiet resilience of winter-flowering hellebores with plantsman John Grimshaw, to the gentle industry of hoverflies with RHS entomologist Josie Stuart, and a summer journey into Britain’s rare temperate rainforests with designer Zoe Claymore, this reflective episode revisits three listener favourites that reveal how even the smallest patches of nature can support a much wider living network.

Oh the weather outside is frightful but there’s still plenty of wonder to be found out there. James Armitage, editor of The Plant Review, joins Gareth Richards to reflect on the quiet beauty of the resilient plants that carry us through the winter months, and on the quiet beauty of seeing familiar plants anew.We begin with writer and plantsman Phil Clayton, who tells the extraordinary story of the Wollemi pine, tracing its journey from near-extinction to gardens around the world. James then sits down with Tom Christian to discuss the remarkable diversity of the ivy family, a group of plants rich in variety and resilience, whose beauty and horticultural value are often underestimated. Finally, we meet South Korean artist Seong Weon Ahn, whose delicate paintings capture plants not only with botanical precision, but with a deep sense of presence and mood.

This week, we honour the stillness of winter and the returning promise of light as we mark the winter solstice. At this turning of the year, we reflect on the people, plants and initiatives that this new light brings into focus. We begin by stepping into the richly curious world of Christopher Lloyd, the influential gardener and visionary behind Great Dixter House and Gardens. His legacy is recalled by his former student and now Head Gardener at Great Dixter, Fergus Garrett. Nick Turrell then returns with his top 10 countdown of plants that changed human history. This time, Nick delves into one species that helped ignite a vast global industry, asking whether its influence has ultimately made our lives better or worse. Finally, a look to the future with Sara Redstone who shines a light on a pioneering initiative taken up by theRHS, focused on strengthening plant biosecurity, highlighting the vital work being done to protect our plants and ecosystems for generations to come.
