Utricularia simplex

Bluecoats

A very small perennial terrestrial bladderwort of section Australes, endemic to south-western Western Australia, where it grows in peaty soil in swampy heath close to sea level. Its tiny rosettes and underground traps live in ground that is waterlogged through the mild, wet winter and dries out in the hot Mediterranean summer, so it is best grown as a sunny, seasonally wet bog plant rather than a tropical terrarium species.

Where it grows wild

Peaty and silty-sandy soils in swamps, seepage gutters and wet low heath with sedges; herbarium notes describe swampy ground in low heath and a grey silty sand runoff channel still flowing from nearby ironstone. Vegetation is low and open, so plants get strong light.

Near sea level to low coastal plain elevations; no GBIF records carry an elevation.
