Distribution

Ecology

Habitat

P. aspera is distributed across southern Georgia and northern Florida [1] and is commonly found in Florida sandhill community.[2] Habitats documented include longleaf wiregrass sandhills, deep sand banks along hardwood hammocks, open pinewoods, longleaf pine/turkey oaks, scrub oak barrens, longleaf pine savannas, sand pine-evergreen oak scrubs, a high bluff, and chestnut oak woods. [3] In disturbed areas it grows in beds of old railroads, roadsides with bahia grass, a clearing of mixed pine-hardwood stand, harrowed areas, bordering fields, and on golf course edges alongside broomsage. [3] Soil types include sand, dry loamy sand, dry clayey sand, gray sand, wet soil, dry sand-clay bank, loam soil, red clay bank and gravelly-clay. [3]

Associated species include Pityopsis flexuosa, Pinus palustris, Aristida stricta, Chrysopsis latisquamea, Chrysopsis gossypina Quercus, Paronychia, bahia grass, Haplopappus divaricatus, Eupatorium pinnatifidum, Lechea, Diodia teres, Dicanthelium, Lespedeza hirta, Polygonella gracilis, Vaccinium arboreum, sandpine, Microcephala, Liatris, Panicum, Leptoloma cognata, Phoebanthus, Scleria ciliata, Helianthus microcephalus, Helianthus atrorubens, Silphium compositum, Eupatorium, Heterotheca latifolia and chestnut oak. [3]

Phenology

P. aspera has been observed flowering in May and from July to December and fruiting have been recorded August through December.[3][4]

Fire ecology

P. aspera occurs in areas with an estimated pre-settlement fire-return interval of 1-3 years [1] and flowers within two months of burning in early summer. [5]
