Gardeners’ Corner looks at the life of Queen Elizabeth II through the lens of all things gardening. David Maxwell chats to those who met her at great gardening events, he visits Northern Ireland’s official royal residence at Hillsborough and explores what her favourite flower, Lily of the Valley, says about her. Also on the programme, Cherry Townsend tells David why sowing now can save you money and get next year’s garden off to a good start.
