Description
"Herbaceous or subligneous, short rhizomatous or stoloniferous perennials. Leaves simple, entire, mostly subsessile. Opposite with bases connected by a stipular line or the upper cauline leaves subopposite, rarely alternate. Inflorescence cymose or paniculate-same length as the tube, tube sinuses semi-transparent; corolla salverform, the lobes cuneate or widely or narrowly obovate to suborbicular, apex entire, erose, or notched; anthers unequally inserted near base of corolla tube and included, or at the mouth of the tube and 1 or more usually exserted; styles 3, almost completely fused or appearing cleft or parted. Capsule papery, subglobose or ellipsoid, 4-6 mm long, loculicdial. A genus of considerable horticultural interest and taxonomic difficulty." [1]
"Slender, erect, flowering stems 2-5 dm tall, often with 2-5 branches from upper nodes, sterile shoots absent or not persistent. Nodes 6-12 on the flowering stems, leaves narrowly lanceolate, the largest 4-8 cm long, 3-8 mm wide, rarely wider, pubescent or glabrate, margins ciliate. Inflorescence open. Calyx 6-12 mm long, the lobes subulate; corolla pink to dark lavender, rarely white, the tube usually pubescent, 11-16 mm long, lobes obovate, 8-12 mm long, apiculate; stamens included; styles cleft ca. ½ their length."

Distribution
Ecology
Habitat
Areas P. pilosa can be found include limestone glades, edge of pine-oak woodlands, pine/hardwood areas, semi-boggy slopes of longleaf pine savanna, burned upland longleaf pinelands and in mesic shaded woodlands by streamlet. [2] Has been found to grow in dry loamy sand. [2]
P. pilosa has been found to grow along highways and the remnants of slightly disturbed woodland habitats. [2]
Associated species include Rhynchospora divergens, Sporobolus vaginiflorus, slash pine and longleaf pine. [2]
Phenology
Flowering has been observed March through May. [2]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [3]
Fire ecology
P. pilosa shows delayed flowering in response to early-season burning. [4]
