Christine Walkden's airborne adventure takes her to Cornwall. At the tropical paradise that is Trebah Garden she's transported back to childhood by the giant Brazilian gunnera and meets Marcus, whose own childhood was spent playing in the garden. Her nerves are tested at St Michael's Mount when she comes face to face with gardening on the edge. And we meet the oldest member of one of Cornwall's oldest male-voice choirs.
