Elizabeth Blackadder, who died last month at the age of 89, was probably the most distinctive botanical artist of our time. Her paintings of lilies and irises, of cats poking their heads imperiously between poppies and freesias, are more alive than any such chocolate-box description could convey. The first woman to be elected to both the Royal and the Royal Scottish academies, Blackadder showed that botanical painting did not need to be twee and parochial.
