Distribution

P. lutea is known to occur in open wet pine savannas.[3] Observed species in sandhill longleaf pine habitat that has 1 to 3 year fire return intervals, on Pebble Hill Plantation (Michelle M. Smith – early summer 2014 and 2015).

Ecology

Habitat

This species has been found in pine flatwoods, boggy areas, and swamp edges.[4] It has been found in open lit areas in drying, loamy sands as well as wet soils.[4] This species has also been found growing in human disturbed areas such as along roadsides as well.[4]

P. lutea increased its frequency and biomass in response to soil disturbance by clearcutting and chopping in north Florida flatwoods forests. It has shown regrowth in reestablished flatwoods that were disturbed by these practices.[5]

Associated species include longleaf pine, cypress, and wiregrass.[4]

Phenology

P. lutea has been observed flowering in January, from March to July, September, and October with peak inflorescence in April.[4][6]

Fire ecology

This species is found in annually burned pinelands[4] such as those of the Wade Tract of south Georgia.[7]
