Acacia auriculiformis, also known as Earleaf or Northern Black Wattle is an Australian native found in the Northern Capes of Australia, in Papua New Guinea and Indonesia.
Some testimonials suggest there may be alkaloids tentatively in the stem bark, but no tests appear to back this. A study on the phyllode extract showed potential in enhancing the memory on rats due to the acetylcholinesterase inhibiting properties of Acacia auriculiformis contributing, to its memory enhancing potential.
For a higher chance of successful propagation of your Acacia, soak the seeds for 48 hours, then sow in a mix of coarse river sand or native potting mix. Keep moist but not wet and germination should take place within 2 weeks. Once germinated, ensure it has excellent drainage and plant in the sunniest spot in the garden. This species has a symbiotic relationship with certain types of soil bacteria and it may be useful to add a heap of soil from underneath a similar local species of acacia. These nitrogen fixing bacteria form nodules on the roots and fix atmospheric nitrogen to share with other plants in the soil. For micro-endemic species, it may be necessary to get a heap of soil from its native landscape for successful growth to occur.
