Can be differentiated from D. annulatum (Kleberg Bluestem) by the pubescence on its inflorescence axis (see photo) and branch bases and foliage that often has a pink or purple tinge. Dichanthium annulatum is not pubescent on its inflorescence axis and branch bases and has pale green foliage. Dichanthium aristatum also appears to be a little smaller and less robust. It is also very similar to Bothriochloa ischaemum (Kings Ranch Bluestem), but the awn at the tip of its lemma is much longer and more conspicuous.
Seeds averaged approximately 565,000/lb.
Poor forage for livestock and wildlife. Good bird nesting and fawning cover (Hatch el al. 1999).
This species has become widespread in drier, warmer parts of Europe. It was introduced to the United States at scattered locations in east Texas and Louisiana as an experimental forage grass. It has apparently become established at a few scattered points in south Texas where it was sown as an experimental forage. It was introduced from southeast Asia and is now widespread in Polynesia, Africa, and Madagascar.
Sometimes used as lawn grass.
