Description
Distribution
Ecology
Habitat
It can live in disturbed areas (e.g., clear-cut, thinned, burned) with clay to sandy loam soil in subtropical climates.[1] It can also dwell in dry areas.[2] It can live in sandstone barrens communities.[2] It can be found in loblolly pine communities[3] as well as longleaf pine communities.[4]
Phenology
Seed dispersal
It can be found in the seed bank of disturbed and undisturbed sites.[4] It can also be found in the seed bank of a Florida flatwoods plant community.[5]
Seed bank and germination
From observing the results of Taft's prescribed burns, fire seems to be required for germination.[2]
Fire ecology
In an experiment by Iglay, Leopold, Miller, and Burger, D. laxiflorum had a positive response to dormant season prescribed fire and imazapyr, a herbicide.[1] Following an early dormant season, moderate-intensity burn in 1989, it rapidly increased, probably due to a stimulation if the seed bank. By 1995, D. laxiflorum occurred in 64% of the quadrats in Illinois and was the species with the greatest frequency, replacing Schizachyrium scoparium as the dominant species.[2]
