ous, it usually blooms later in the year and it has paler flowers than ''Acacia longifolia.'' It flowers usually from December through February. Some populations of ''Acacia obtusifolia'' can survive winters to −6 °C and possibly a light snow, however plants from populations in areas that are frost free such as the coastal ranges of Northern NSW are susceptible to cold and will be killed by frosts lower than −3 °C. These populations avoid the valley floors and occur mainly on sandstone ridges well above the frost line.

, can be isolated from ''A. obtusifolia'' heartwood. Net lore indicates a 0.45% average dimethyltryptamine in the bark and 0.3% in the dried young leaves. Similarly, Mulga states figures ranging from 0.4% to 0.5% in the dried bark, noting there to be some variability. No formal scientific publishing of phytochemistry, several chromatographs show 0.3% alkaloid consisting 2:1 monomethyltryptamine, dimethyltryptamine, plus trace betacarbolines; another found additional 5 methoxydimethyltryptamine and gramine.
