🌿 Acacia iteaphylla
Willow Acacia with Soft Yellow Blooms
Acacia iteaphylla, commonly known as Willow Acacia, is an elegant Australian native shrub appreciated for its graceful, willow‑like foliage and profusion of softly fragranced pale yellow flowers. The long, narrow phyllodes create a gentle, flowing texture, while the rounded flower clusters add seasonal brightness from late winter through spring.
Adaptable and drought tolerant, Acacia iteaphylla thrives in full sun and fast‑draining soils. It is well suited to water‑wise landscapes, coastal gardens, and Mediterranean‑style plantings, offering light screening, movement, and dependable performance with minimal maintenance once established.
