Swainsona perlonga is a scrambling perennial pea from inland south-western Western Australia, grown mainly by native plant enthusiasts for its purple to lilac-pink flowers. It is a species, not a genus, and is a low-maintenance plant in its native dry, clay-rich conditions.
Swainsona perlonga is a species of flowering plant in the family Fabaceae and is endemic to inland parts of the south-west of Western Australia. It is a scrambling perennial herb with imparipinnate leaves with 7 to 13 egg-shaped or almost round leaflets, and racemes of 7 to 10 purple to lilac-pink flowers.
This species of pea grows in clay on river banks, and swampy or saline areas, in the Geraldton Sandplains, Murchison and Yalgoo bioregions of inland, south-western Western Australia.
