Discussion
Schizachyrium scoparium var. stoloniferum grows in sandy soils of woodland openings and roadsides from southern Alabama and Georgia south to the Everglades. Northern populations consist of widely spaced, weak culms growing in rather bare sand; southern populations consist of dense, vigorous stands with taller, more robust culms growing primarily along roadsides, possibly spread by grading equipment. Some clones, particularly in the south, are largely sterile.
