Earleaf Acacia Seeds

Landscape Rating: ⭐⭐⭐⭐⭐ (5/5 Stars)

Plant Characteristics

Earleaf Acacia is a fast-growing evergreen tree native to Australia, Papua New Guinea, and Indonesia. It is widely admired for its graceful form, attractive curved foliage, bright golden flowers, and exceptional adaptability to difficult growing conditions.

Unlike many acacias that possess finely divided leaves, Earleaf Acacia develops unique sickle-shaped phyllodes (modified leaf stems) that resemble large curved leaves. These glossy green phyllodes create a lush tropical appearance and provide year-round beauty.

Mature trees typically reach 30 to 50 feet in height with a broad, rounded canopy. During the flowering season, the branches become decorated with masses of fragrant golden-yellow flower spikes that contrast beautifully against the dark green foliage.

Its rapid growth, attractive appearance, and tolerance of heat make it a valuable specimen lawn tree in warm climates.

Landscape Uses

• Specimen lawn tree
• Shade tree
• Tropical landscapes

• Windbreaks
• Reforestation projects
• Wildlife landscapes
• Street tree plantings

Its dense canopy and attractive foliage make Earleaf Acacia especially useful where quick shade and year-round greenery are desired.
