Purpletop Rhodes grass

Purpletop Rhodes grass is an annual or periennial with a tufted growth habit, ranging in height from 20 to 100 cm tall. Leaves range from 4 to 40 cm long and 2 to 5 mm wide, while the purple coloured seed heads form at the end of stems. This grass can be found growing in a range of soil types and is known to be tolerant of saline and dry soils. In the north of Australia, it can be found growing in seasonally wet areas such as claypans, river flood flats, creek beds and banks (Cape York NRM). Sugar Research Australia information report that it is widespread and common in areas of poor soil and its presence can indicate soil that is saline or sodic. It also grows on highly compacted soils. It is reported to be an aggressive invader of degraded land and will outcompete other species. It can be commonly found in gardens, parks, orchards, cultivation, degraded sites and pastures. Some data indicates this plant might have allelopathic properties - reduced growth of other plants.
