This week the castaway on Desert Island Discs is Lady Walton. Within two weeks of meeting the composer Sir William Walton, Susana Gil Passo had accepted his marriage proposal and left her home in Argentina. When they moved to the island of Ischia, she began transforming the barren land into what is now La Mortella - one of the most famous and beautiful gardens of the Mediterranean. It boasts more than 600 exotic plants - including tree ferns, jacaranda and the huge Victoria Amazonica Waterlily - and is the backdrop to summer concerts organised in Sir William's memory. In conversation with Sue Lawley, she talks about her life and work and chooses eight records to take to the mythical island.
