Naturalised in some parts of south-eastern Australia (i.e. on the central and southern tablelands of New South Wales and in the ACT).
Wavyleaf barberry (Mahonia pinnata) is regarded as an environmental weed in south-eastern New South Wales and as a "sleeper weed" in other parts of south-eastern Australia. This species is often cultivated as a garden ornamental in temperate regions. It produces small grape-like fruit and is spread into natural areas by birds.
Wavyleaf barberry (Mahonia pinnata) was first recorded as naturalised in New South Wales in 1987, and is an occasional weed of gullies in the Blue Mountains and Southern Tablelands regions of this state.
