Nick Knight shared a series of photographs from his acclaimed project ‘Flora’ with Willows, an older people's unit in Woodlands. The project was first initiated in 1993 for Knight’s installation ‘Plant Power’ at the Natural History Museum in London and then became a book, of the same name, which is a daring and comprehensive volume of 46 images of flowers and plants chosen from the Museum’s six million specimens. To create the collection, Knight and his wife, Charlotte, spent three and a half years in the herbarium mapping the presence of flora - from opium to cotton - in our society.
