Panicum hirstii is a stiffly erect panic grass that grows 20 - 60 cm (8 - 23 in) tall. The taxon inhabits sandy pine woods and pond shores of the coastal plain barrens of New Jersey, Delaware, and North Carolina. It is also found in limestone depression ponds and shallow Cypress ponds of Georgia. Threats to this species come mainly from habitat alteration for development and changing hydrology of coastal ponds.

Research and Management Summary:
Taxonomic work and germination studies have been performed for this species, and some monitoring of populations has occurred.

Plant Description:
Panicum hirstii grows from clustered culms. The inflorescence, or panicle, is 3-10 cm (1-4 in) long and sparsely flowered with finely hairy spikelets; panicles sometimes stay hidden among the densely branched stems.
