''L. tenuifolia'' responds positively to conditions following a burn by increased vegetative growth and flowering and typically blooms within a year or so following fire (Anderson and Menges 1997).

Description
A description of Liatris tenuifolia is provided in The Flora of North America.
Distribution
Ecology
Habitat
Habitats of L. tenuifolia include longleaf pine-turkey oak sand ridge, dry Quercus laurifolia hammock, scrub-oak ridge, sandhills, semi-boggy areas, wet pine flatwoods,course sand and scrub oak barren, and annually burned pinelands (FSU Herbarium). Human disturbed areas include moist loamy sand of roadside depression, dry sand of scrubby ridges along roads, bordering pine flatwoods along the road, sandy clearings, open fields, and on the edge of clearing banks of rivers (FSU Herbarium).
Soil types observed include moist loamy sand, dry sand, coarse sand, gravelly sandy soil, white sand, sandy loam, and sandy-peaty soils (FSU Herbarium). Availability of nitrogen, pH, organic matter, and inorganic nutrients such as (Ca, K, Mg, and P) have been observed to be concentrated at low levels in the soil (Anderson and Menges 1997).
Phenology
Flowers have been documented blooming in September through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire improves seedling recruitment (Whelan 1970).
Fire ecology
L. tenuifolia responds positively to conditions following a burn by increased vegetative growth and flowering and typically blooms within a year or so following fire (Anderson and Menges 1997). There is an increase in growth and flowering in burned sandhill sites located in south-central Florida (Anderson and Menges 1997). It also has been found in burned and unburned patches of degraded longleaf pine sandhill (Heuberger and Putz 2003).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Liatris tenuifolia at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus
Halictidae: Agapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa
Megachilidae: Coelioxys mexicana, C. sayi, Megachile albitarsis, M. brevis pseudobrevis, M. brimleyi, M. petulans, M. texana
Sphecidae: Ammophila procera
