Episode 15 - S54.E15

We join Adam Frost in his garden, where he will be giving tips on laying turf, planting succulents and adding perennial plants to his kitchen garden to grow as cut flowers. Joe Swift travels to Marwood Hill Gardens in Devon to explore plants that thrive in moist conditions, and in Buckinghamshire, we uncover the story of a hidden collection of iris accumulated over a period of 45 years. In Midlothian, we visit a nursery where the Himalayan blue poppy is a speciality, and Frances Tophill meets a florist who has a passion for growing cut flowers on her allotment. Carol Klein visits Trebah Garden in Cornwall, where she finds plants which can add early summer pazazz to our borders. Nick Bailey is at RHS Wisley to look at a variety of shrubs that can be used as alternatives to traditional box hedging. We travel to the seaside in Kent to meet a group of gardeners who have transformed an unloved public space, and in Wales, we find a garden packed with unusual and prehistoric plants.
