About

Agonis flexuosa, commonly known as peppermint, is a species of flowering plant in the family Myrtaceae and is endemic to the southwest of Western Australia. The Noongar peoples know the tree as wanil, wonnow, wonong or wannang. It is a tree or shrub with pendulous, very narrowly elliptic, narrowly elliptic or narrowly egg-shaped leaves, white flowers with 20 to 25 stamens opposite the sepals and broadly top-shaped to broadly cup-shaped capsules.

Where it grows

Agonis flexuosa var. flexuosa occurs in a range of habitats from coastal heath to woodland or forest and in a range of soils, in the Esperance Plains, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia, and var. latifolia mainly grows in sandy soil in heath, shrubland or woodland between Walpole and Cheyne Beach in the Esperance Plains, Jarrah Forest and Warren bioregions, with a record from the Stirling Range.
