Binarail is a plant which grows from 20 to 80 centimetres with green leaves and white to light purple flowers growing in clusters from February to October.

The Wurundjeri-woiwurrung used their leaves as a herb as well as medicinally. Like its common name suggests, it has a mint-like taste.

It grows in moist to wet soils in full sun to full shade, typically near watercourses.
