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

Genus:Agonis

Species:flexuosa

Family:Myrtaceae

Willow myrtle features gracefully drooping branches and leaves with a distinctive copper underside, thriving in the temperate coastal regions of western Australia. This species flourishes in moist, sandy soils under full sunlight but can adapt to various conditions, provided the soil is well-drained. Once established, it demonstrates resilience to drought and exhibits a commendable tolerance to salt.

The leaves are elongated and slender, while the flowers bloom in small clusters along the stems during the spring season. Mature specimens display a characteristic weeping form, making this tree an excellent choice for warm coastal environments with mild winters, particularly in USDA hardiness zones 9 and above.
