Utricularia violacea is a terrestrial bladderwort endemic to southern Australia. The species derives its name from its violet coloration.
The blooms are relatively small in size, typically reaching around half a centimetre in width. The lower corolla lip is divided into three shallow lobes. The upper corolla lip has two lobes separated by a rounded notch. The corolla spur is broad at the base and steadily tapers towards the extremity. The flower is violet in coloration, with a yellow patch at the palate and dark purple streaks surrounding it.
Utricularia violacea is found in the southern states of Australia. The species occupies sandy seepages and grows as an annual, persisting in the environment as seed over the dry summer. In Victoria, it is restricted to heaths close to the border with South Australia where it is naturally rare. I found the plant growing in a seepage formed by a ditch at the intersection of a road and a creek. It is relatively common in Western Australia.
