Narrative
Fourchon bitter panicum is intended for use on coastal beaches and barrier islands of the north central Gulf coast, primarily Louisiana, Mississippi, and Texas. It is an early colonizing species that grows best on the crest and windward slope of the foredune where few other species compete with it. It is a warmseason native perennial grass that spreads primarily by rhizomes or by tillering from lower nodes on the culm (stem).
