Sturt's Desert Pea is an Australian plant in the genus Swainsona. One of Australia's best-known wildflowers, it is known for its distinctive blood-red leaf-like flowers, each with a bulbous black centre, or "boss". It is native to the arid regions of central and north-western Australia, and its range extends into all mainland Australian states with the exception of Victoria. It is the floral emblem of South Australia.
