The Queensland silver wattle (Acacia podalyriifolia) belongs to Mimosaceae (the Mimosa family). It is a small evergreen tree that is native to south-eastern Queensland, Australia. This tree grows in open forests and woodlands, and can reach about 5 m in height. It does not have true leaves but has leaf-like flattened stems called phyllodes. They are silvery gray and oval in shape. The golden yellow flowers bloom in ball-shaped clusters in the axils of the phyllodes from late winter to early spring.
