Tufted perennial with erect habit; to 120cm however can be much shorter where fertility has run down.

Dichanthium sericeum is well known on fertile, black, self-mulching clay loams however we encounter it on a range of heavy soils of moderate fertility where like many native grasses it is facing increasing competition from exotic grasses. Nonetheless it has proved persistent and we attribute much of this to its ability to produce very large quantities of highly viable seed. Heavy grazing can reduce or eliminate some exotic pastures, possibly moreso where soil phosphorous is below optimal. This creates opportunity for D. sericeum to once again dominate the pasture ecology. Providing seed has been allowed to ripen and fall to ground in Summer or Autum, a Queensland Bluegrass pasture will regenerate very efficiently after rainfall.

Queensland Bluegrass may be cut for hay.

"Considered to be a good fodder grass" (Stanley and Ross, 1989).

Infraspecific taxa are recognised within Dicanthium sericeum, namely subsp. sericeum, subsp. humilius, subsp. polystachyum. The latter two are described as annuals.
