Distribution
P. lutea is known to occur in open wet pine savannas. [2] 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

[3] This species has also been found growing in human disturbed areas such as along roadsides as well. [3] Associated species include longleaf pine, cypress, and wiregrass. [3]
Phenology
It has been observed flowering in April, May, July, and September. [3]
Fire ecology
This species is found in annually burned pinelands. [3]
