Last summer I was staying at a house in Hampshire which was famous for the brilliance and the originality of its gardens. There were many of them, but the most beautiful of all was a walled garden in which every flower was blue. There were all the obvious things like delphiniums and acronitums and larkspurs, but the most beautiful blue of all came from the groups of cabbages – the ordinary blue pickling cabbage. Set against the blazing blue of the other flowers, it had a bloom and elegance which made it a thing of the greatest delight.
