Indian bluegrass is an exotic grass naturalised in many parts of Queensland; it can also be found growing in the Northern Territory and to a lesser extent Western Australia; Indian bluegrass was introduced into Australia in the 1930s and in 1950, with genotypes coming from India and to a lesser extent, Africa (Spiegel, 2016). Many of the genotypes differ in the growth and habit, along with their reproduction method e.g. prolific flowering and seeding. The weed is commonly seen along footpaths and parks within older suburbs.
