Swan River Peppermint Agonis flexuosa

Phonetic Spelling
AG-on-iss fleks-yoo-OH-suh
Description

Willow myrtle has weeping pendulous branches and copper backed leaves and is native to mild coastal climates and habitats of western Australia. It prefers moist sandy soils in full sun but is adaptable as long as the soil is well-drained. It is drought tolerant once established and has good salt tolerance.

The leaves are long and narrow and the flowers occur in small clusters along the stems in spring. Mature trees have a weeping habit. This is an appropriate tree for warm coastal areas with mild winters in zones 9 and higher.
