Plumerillo (Jarava plumosa) is a potential weed of pastures, native grasslands and open woodlands in the temperate regions of Australia. Its is one of eleven exotic stipoid grasses that are thought to pose a significant threat to remnant indigenous grasslands in south-eastern Australia and its potential distribution in this country has been estimated at about 1.8 million hectares.
Plumerillo (Jarava plumosa) was introduced as a potential pasture plant in the early 1940s, but it has since been found naturalised in the vicinity of the Waite Institute in Adelaide in south-eastern South Australia. While it appears to be spreading, it is so far confined to this one general area and populations are controlled on an ongoing basis.
