Callicoma serratifolia is naturally found in Australia growing in coastal regions from southern Queensland to New South Wales, appearing in sheltered moist gullies, commonly along creeks. 

It prefers a well drained moderately fertile sandy soil with added leaf mould and grows in a semi shaded position but will tolerate full sun and is drought, frost and salt laden wind tolerant.

Black Wattle is grown for its foliage and flowers. It is planted along watercourses and used in bush regeneration programs where storm water runs. It is also planted in garden borders for screening and used in damp positions. It is suitable for coastal and the adjoining tablelands and establishes in 2 to 3 years. ID 554

Note:
Callicoma was the first wattle seen and used by the English settlers. The flowers and habit is simular to some Acacia species but the two plants are unrelated.
