Agonis flexuosa

The Agonis flexuosa, commonly known as the “Willow Myrtle” or “Peppermint Tree,” is the most prevalent species of the Agonis genus and is widely found in South Australia, particularly in parks and along roadsides. This small evergreen tree boasts a short, brown, grooved trunk relative to its overall size. The foliage consists of small, green, shiny leaves with a copper-colored underside, emitting a pleasant fragrance often likened to mint.

The tree’s canopy has a distinct weeping appearance, adding a graceful touch to any landscape. In spring, the Agonis flexuosa produces clusters of small, white flowers nestled among its branches. These blooms give way to hard, woody fruit.

Similar to Eucalyptus, Agonis flexuosa can inhibit the growth of surrounding vegetation, which should be considered when planting. Once established, the tree is quite water-efficient and thrives in well-drained soils. However, overwatering can lead to root rot and eventual collapse, so it is crucial to avoid excessive moisture. The tree is adaptable to sandy and saline soils and can be planted in coastal areas, tolerating second and third-line sea exposures.

The Agonis flexuosa responds well to trimming and shaping, making it suitable for street planting and areas with overhead power lines. Its sculptural form, reminiscent of a willow, combined with its resilience to various conditions, makes it an attractive and functional choice for diverse landscaping needs.
