Notes
Narrow-leaved blue lupin (Lupinus angustifolius) is regarded as an environmental weed in Western Australia. This species is grown as a fodder and grain plant and is mainly a weed of agricultural areas and habitation (e.g. disturbed sites, waste areas, roadsides, parks and croplands). However, it has also become naturalised in disturbed natural vegetation, sandy coastal habitats and open woodlands.
Narrow-leaved blue lupin (Lupinus angustifolius) is a weed of road verges and woodlands from Geraldton to Albany and is listed as a minor environmental weed in the Environmental Weed Strategy of Western Australia. It is also widely naturalised in New South Wales, where it is often found growing in open eucalypt woodlands.
