Description

''Acacia obtusifolia'' is an upright or spreading perennial tree, which grows from 1.5m to 8m in height and is native to Australia. It is closely related to '' Acacia longifolia''. ''A. obtusifolia'' can be distinguished by having

phyllode Phyllodes are modified petiole (botany), petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode co ...

ous, usually blooming later in the year and with paler flowers than ''A. longifolia.'' It flowers usually from December through February. Some populations of ''A. 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.
