Distribution
Ecology
Habitat
This species is found in pine flatwoods, evergreen scrub oak sand ridges, fallow fields, bordering swamps, and longleaf pine-wiregrass pinelands. [1] Also found in disturbed areas, Lactuca graminifolia has also been observed to grow along roadsides, near campgrounds, around parking compounds, and within moist, sphagnum-filled ditches. [1] It grows in dry, loamy sands as well as moist, grassy areas in open light conditions. [1] Associated species includes Longleaf pine, wiregrass, Phlox floridana, Stillingia sylvatica, Asimina longifolia var. spathulata, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocaulon undulatum, Asclepias humistrata, and Quercus hemisphaerica. [1]
Phenology
This species has been observed flowering from March through July and in October. [1] It has also been observed fruiting from May through June and in October. [1]
Fire ecology
It is found in patches of degraded longleaf pine sandhill after burn and control (no burn) treatments.[2]
