It blooms between April and January producing simple inflorescences in both axillary and terminal panicles and racemes on stalks that are in length. The spherical flower-heads have a diameter of and contain 14 to 20 pale yellow flowers.

In the Dharawal story of the Boo’kerrikin Sisters, one of the kindly sisters was turned into Acacia parvipinnula. The other two sisters were turned into Acacia decurrens and Acacia parramattensis.[2]
