Midwinter Gardens: Influential Plants, Christmas Trees and New RHS Gardens

The new year has arrived with an Arctic blast, and so it feels like the perfect moment to retreat indoors and let the garden live in our imaginations for a while. Nick Turrell joins us to continue his countdown of the most influential plants that have shaped human history. Guy Barter shares his practical ideas for making the most of your Christmas tree in the garden, and Pru Murray takes us through some of the new partner gardens RHS members can enjoy visiting in 2026.

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.

This week, RHS Head of Libraries Fiona Davison, garden designer Zoe Claymore and RHS Gardening Advisor Nick Turrell gather to share their must-read gardening books of 2025. Along the way, they explore what really makes a garden waterwise, dive into the astonishing world of fungi, demystify regenerative gardening, and get to the root of soil science. They also journey through the makings of a temperate rainforest, spotlight remarkable horticultural heroes from history — and yes, they even tackle the topic every gardener loves to hate: slugs.

December is the perfect time to take stock of the garden and dream of the seasons ahead. With this in mind, this week we’re bringing you some extraordinary stories from horticulturists past and present. Fiona Davison kicks things off with the astonishing tale of Muriel Howarth, who passionately advocated for the potential of atomic energy in gardening. Nick Turrell then joins us to unveil the first two entries in his top ten most influential plants: species that have shaped history through their extraordinary abilities and dramatic backstories. And finally, Helen Bensted-Smith returns with the concluding chapter of the wildlife ponds mini-series, guiding you through how to keep your pond healthy and thriving for years to come.

It’s National Tree Week, and we’re heading into the woods to celebrate the trees that shape our landscapes, enrich our lives, and quietly support the world around us. We’re joined by Sally Bavin from the Woodland Trust, who explains why woodlands are so powerful for both our physical and mental wellbeing. She also shares her fascinating research into mapping the UK’s richest areas of “wellbeing woodland.” We’ll also dive into the RHS’s new Strong Roots report, which uncovers the challenges preventing Great Britain from growing the trees it needs for the future. Plant scientist Louise Jones takes us behind the scenes at the RHS to explore her investigation into a mysterious fungal pathogen that’s attacking lime trees. And finally, we continue our pond series with Helen Bensted-Smith, who reveals the wildlife you can spot around your pond this week.

As frosts arrive across the UK – later than usual this year – we’re exploring how to give nature a helping hand when the seasons fall out of step. In this installment of our wildlife ponds mini-series, Helen Bensted-Smith walks us through her top planting recommendations for different aquatic habitats. Wisley Garden Manager Mark Tuson also reveals how his team turns fallen leaves, cuttings, and woody material into valuable resources that enrich the soil, strengthen plant health, and boost biodiversity. Finally, we head to East Sussex for a tour of the iconic Arts and Crafts gardens at Great Dixter – home of the late garden writer Christopher Lloyd – guided by Head Gardener Fergus Garrett.

All life begins with water — and in gardens across the UK, ponds are becoming vital sanctuaries for wildlife. Now is an excellent time of year to create one, and RHS expert Helen Bensted-Smith walks us through everything you need to know: from position and depth, to lining material, structure, and how to fill it! It’s the first in our four-part mini-series on making your own wildlife haven this autumn — starting from the ground up with tips on planning, design, and making your pond truly work for nature. Plus, Emma McFarline returns to share the fascinating histories and healing traditions of two timeless plants — the apothecary rose and chamomile — and Duncan McLean offers expert advice on finding the perfect indoor plant to brighten up your home through the November chill. From ponds to petals and everything in between, it’s a celebration of how nature connects us — indoors and out.

This week we’re taking a moment to look ahead. Carol Barrie from the RHS  Science and Collections Department joins us to talk about Plants for Purpose, an ambitious new project she’s leading in collaboration with the University of Nottingham. It’s using the power of AI, alongside the RHS’s vast Herbarium, to build a living knowledge bank of plants that benefit the environment. We’ll also turn our gaze to spring, as now’s the perfect time to get tulips in the ground before the ground gets too wet or freezes. We revisit Arundel Castle, where back in 2022, 80,000 tulip bulbs arrived for a spectacular spring display. And finally, we head to RHS Rosemoor to meet Emma McFarline, who’ll be exploring the practical, and sometimes surprising, uses of familiar garden plants, from their roles in history to their value today.
