Dichanthelium caerulescens se documenta por primera vez en Louisiana, como resultado del trabajo de campo florístico realizado en 2019 hasta 2021. Los registros de Louisiana amplian el rango de D. caerulescens hacia el oeste en aproximadamente 265 millas (426,5 km) en la ecorregión de la llanura costera occidental del Golfo. Estos hallazgos también identifican un nuevo hábitat, la pradera costera, utilizada por D. caerulescens.
