The Cleveland Museum of Art is hosting an exhibition entitled Painting the Modern Garden: Monet to Matisse now through January 5, 2016. The exhibition, organized by CMA and the Royal Academy of Arts in London, looks at the role of gardens to artists such as Claude Monet, who was also a horticulturist.
The Poisoned Cup (aka "Carrying a Peacock") by John Dawson-Watson, 1869
Another artist discovered via Pinterest. John Dawson-Watson was a British Impressionist whose early work seems very similar to John Everett Millais of the Pre-Raphaelite Brotherhood fame. The rich colors and attention to detail found in this work becomes looser and more pastel after he studies Impressionism at Monet's home in Giverny.
