Gardens are more than places of beauty — they’re living archives, preserving stories of the past. In this episode, we leaf through the September issue of The Plant Review to uncover what history can teach us about the gardens of today. RHS horticulturist Jack Aldridge recalls the rare purple-leaved Stachyurus—first spotted in a Devon garden in the 1970s, lost for decades, then rediscovered at a Cornish plant fair. Judith Taylor, a 91-year-old retired neurologist and garden historian, explores the legacy of Roy Genders, one of the most prolific gardening voices of the 20th century. And plant taxonomist and collector Jamie Compton joins James to untangle the thorny mysteries of the Banksian roses.
