To cope with desert conditions, plants must be able to withstand not only extremely hot, dry conditions, but also the bitterly cold nights that characterise the desert environment. Excellent drainage is generally essential and usually sandy soils are preferred.

Swainsona formosus (Sturt's Desert Pea) - low spreading Australian plant; attractive soft hairy grey-green leaves; spectacular flowers typically red with a black central bump, but many colour variations have been developed including pink, white and bi-colours; floral emblem of SA; often treated as an annual.
