Swainsona oliveri is a small, low, sprawling herb in the pea family from arid Australia, usually grown only as a specialist native or for seed. The key to growing it is full sun, very free-draining soil and minimal water, mimicking its desert habitat.
Swainsona oliveri is a species of flowering plant in the family Fabaceae and is endemic to south-western Australia. It is a slender, prostrate to ascending annual or perennial herb with imparipinnate leaves with 9 to 13 narrowly egg-shaped leaflets, the narrower end towards the base, and racemes of up to 4 cream-coloured to yellow flowers, sometimes with a pink tinge.
This species of swainsona grows on sandy plains and is widespread in South Australia and in the Avon Wheatbelt, Coolgardie, Great Victoria Desert, Hampton, Murchison and Nullarbor bioregions of Western Australia. It also occurs in the far western plains of New South Wales and the south of the Northern Territory.
