Prostanthera cuneata, commonly known as Alpine Mint Bush or Rough Mint Bush, is native to south east Australia. In its native habitat it grows alpine heath and shrub land.

The etymological root of the binomial name Prostanthera is derived from the Greek prostheke menaing ‘appendage’ and anthera menaing ‘anther’. Cuneata is  from the Latin meaning ‘wedge shaped’.

Ecologically, Prostanthera cuneata flowers are attractive to pollinating insects.
