Agonis flexuosa, the Willow Myrtle or Peppermint Tree, is a graceful evergreen Australian native grown for its weeping canopy of narrow aromatic foliage that releases a distinct peppermint scent when crushed. It delivers effective shade and screening with timeless elegance.
Willow Myrtle grows to 8-15 metres tall and 4-6 metres wide with a soft weeping habit. The scale and coverage suit coastal, urban, and rural landscapes, working well as a feature tree, informal screen, windbreak, or street tree. White flowers appear along the branches in spring, attracting birds and pollinators.
Willow Myrtle is highly drought tolerant once established and excels in exposed coastal conditions, handling salt-laden winds and sandy soils with ease. It performs best in full sun to part shade across WA, SA, VIC, NSW and southern QLD, tolerating light frost once established.
Green species or Burgundy cultivar? This is the green-leaved Agonis flexuosa species, a larger tree at 8-15m suited to shade, screening, and street use. For a more compact garden feature with rich burgundy-purple foliage, see Agonis flexuosa 'Burgundy', which grows to 5-7m.
