Sandi Toksvig meets Paul Smith, Head of The Millenium Seedbank at Wakehurst Gardens in Sussex and horticultural expert Mark Griffiths. Together they explore the world looking for seeds to bring back to the UK for classification, analysis and planting. Sandi also meets Sofia Koutlaki, a writer and linguist, who tells her about exploring Iran. Plus travel writer Nick Maes discusses his recent visit to the Musandam peninsula, very near to Iran but a world away in The Strait of Hormuz.
