Natural habitats for the P. pycnostachyum include sandhillas, dry pinelands, dry praire, and pine flatwoods. [3] [2] Specimens have been collected from bay forests, pine savannas, bog remnants, loose sand on burned pine flatwoods, longleaf pine regions, dry scrub woods, wiregrass savanna, coastal hammock, cypress flatwoods, moist savannas, slash pine palmetto, cyrillo swamp, and open pine flatwoods. [4]
Pterocaulon pycnostachyum can be found in the same habitats as Deeringothamnus rugelii, Asclepias pedicellata, Aristida beyrichiana, Asimina reticulata, Cuthbertia ornata, Galactia elliotti, Lygodesmia aphylla, and Pinus palustris. [5]
