Origin: | Tropical America |
Notes: | Spread by: water and contaminated soil. Invades/threats: coastal communities, open forest, disturbed areas, creek lines, roadsides and pastures. Notes: native of Tropical America. May be an aggressive weed in pastures but no records of this happened in this region. Two introduced species are naturalised in this region, particularly in coastal sites, but there are also native Indigofera species so correct identification is essential, especial for managers of environmental areas. The majority of species have nitrogen fixing nodules on their roots. Environmental weed. |
