A tough, fast-growing native for tropical resilience, shade, and soil repair.
 
Acacia auriculiformis, also known as Earleaf Wattle or Northern Black Wattle, is native to the Northern Cape of Australia, as well as parts of Papua New Guinea and Indonesia. It is a hardy pioneer species used in revegetation, nitrogen-fixation, and erosion control, thriving in tropical and subtropical climates with poor soils, heat, and seasonal dryness.
 
Anecdotal reports suggest possible alkaloids in the stem bark, though no formal phytochemical analyses confirm this. A published study on the phyllode extract showed potential memory-enhancing properties in rats via acetylcholinesterase inhibition—suggesting this tree may hold neuroprotective qualities worth further exploration.

Propagation Notes:
Soak seeds in warm water for 48 hours to break dormancy
Sow in coarse sand or native potting mix
Keep moist (not wet) — germination should occur in 1–2 weeks
Requires full sun and excellent drainage
May benefit from adding soil from beneath a healthy local Acacia to introduce symbiotic nitrogen-fixing bacteria
