Study of red-edged pig's ear, cotyledon orbiculata

Peter Brown, botanical and natural history artist, may have studied under Georg Dionysius Ehret (1708-70), whose style is similar. Following in the botanical tradition, he painted in watercolour on vellum, as its smooth surface allowed very fine detail and gave a realistic sheen to leaves and petals.
Brown taught a number of aristocrats before being appointed Botanical Painter to the Prince of Wales in 1784. He was also patronised by Lord Bute, who advised on the development of the Royal Botanic Gardens at Kew, and it is possible that he painted this and other botanical watercolours there. He exhibited at the Royal Academy from 1770 to 1791.
