Gardening with the RHS

We’re marking National Tree Week, an annual celebration at the start of the tree planting season, and an opportunity for us to wax lyrical about the wonderful world of trees. We’ll be hearing some fascinating stories about the art of tree collecting and the human connection to our woodlands from author and artist Amy Stewart. We’ll be catching up on the latest news from RHS Garden Rosemoor as they set out on a conservation project to protect one of our most rare but little known native trees.

This week we explore the fascinating stories and brilliant work of three exceptional plantswomen. Only recently has pioneering 18th-century herbalist Elizabeth Blackwell received proper recognition for her work A Curious Herbal – a beautifully illustrated botanical text that was, for centuries, mistakenly attributed to her scandal-prone husband! Fiona Davison, Head of RHS Libraries & Exhibitions, shares insights into Blackwell’s life and her groundbreaking work, which was created at a time of rapid botanical discovery in Europe as exotic plants flooded into the Western world. We also hear from passionate plantswoman Jane Steward, a dedicated advocate for the medlar, a rare fruit that was once beloved across the UK – even by King Henry VIII. And finally horticulturist Sarah Wilson-Frost from RHS Garden Hyde Hall will be sharing some excellent advice on growing ornamental grasses to add year-round interest to your garden.
