Acacia auriculiformis or the Northern Black Wattle is a large evergreen tree with dense foliage and a spreading crown.
It is fast growing and has a fairly shallow, densely matted root system that make it suitable for land stabilisation and erosion prevention.
It is a good shade tree more useful in parks, public areas and farmland and is also a tough tree being both tolerant of drought and poor soil, however as with many Acacia it doesn't have a long life span.
It has long, slightly curved leaves (10-20cm), these are not true leaves but flattened, blade-like phyllodes The fluffy, mimosa-like flowers are golden, sweet scented and borne on cylindrical spikes from the leaf axils pods.
The seed pods are straight when young but twist and curl as they mature, hence the common Earleaf Acacia.
Used by aboriginals as fish poison by crushing the seeds and also for making soap from crushed seed pods.
