Charles Sturt is remembered in Australia with many memorials. There are rock cairns and signs that show many of the places he explored. Two plants were named after him, Sturt's Desert Pea (Swainsona formosa), the floral emblem of South Australia, and Sturt's Desert Rose (Gossypium sturtianum), the floral emblem of the Northern Territory. Sturt found the plant in creeks near the site of Broken Hill, New South Wales in 1844. He collected the seeds and brought them back for Robert Brown (1773–1858), a Scottish botanist, to study.
