Swainsona decurrens is an erect annual pea from arid northern inland Western Australia, grown for its racemes of red or purple flowers. It is a wildflower of desert sand and gravel, not a common garden plant, so growing it means matching its dry, sandy habitat.
Swainsona decurrens is a species of flowering plant in the family Fabaceae and is endemic to northern inland areas of Australia. It is an erect annual with imparipinnate leaves usually with 15 to 19 narrowly elliptical leaflets and racemes of 20 to 30 red or purple flowers.
This species of pea grows in sandy or stony soil in the Gascoyne, Little Sandy Desert and Pilbara bioregions of northern inland Western Australia.
