Four years ago, the Royal Academy had an exhibition I reported on called Painting the Modern Garden ("Monet to Matisse"). I enjoyed it immensely (I think I went twice): the RA know how to put on a great show. The Monet water lilies in the last room were like being before an altar. Quite magical.
The Academy have just put their film of the exhibition on YouTube. Beautifully produced and full of colour as you would expect. This is worth putting up on a big screen and sitting back to wallow in: much art and beautiful plants.
