Description
A description of Liatris gracilis is provided in The Flora of North America. Liatris gracilis is a perennial herbaceous species. Its stems are pubescent with leaves that are glabrous or pubescent beneath and remotely ciliate. The involucres are pedunculate, cylindric, 5-9 mm long, and 3-7 mm in diameter. The heads are 7-12 flowered with 1-3 cm long peduncles. The nutlets are 2.5-4 mm long with pappus that are 5-6.5 mm long.[1]
The root system of Liatris gracilis includes corms which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[2]. Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 370.3 mg/g (ranking 9 out of 100 species studied) and water content of 43.8% (ranking 19 out of 100 species studied).[2]
Distribution
This plant ranges from Southern Carolina, south to southern Florida, and west to Mississippi.[1]
Ecology
Habitat
L. gracilis occurs in moist to dry loamy sand, sandy loam, or sandy clayey soils.[3] It can be found in longleaf pine-wiregrass flatwoods communities, mixed oak-pine woodlands, oak scrub, grasslands, sandhills, limestone outcroppings, and dry hammocks.[3] However, it can also be found in disturbed areas including roadsides, clear-cuts, waste ground, power line corridors, and old fields.[3] Associated species include Liatris elegans, L. chapmanii, L. spicata, L. tenuifolia, Agalinis, Trichostema, Dicerandra, Pinus palutris, Pinus clausa, Carphephorus pseudoliatris, Carya, Pinus elliottii, Carphephorus odoratissimus, C. paniculatus, Chrysopsis, Chrysopsis, Eupatorium, Solidago, Palafoxia, Aristida stricta, Myrica, Quercus virginiana, Serenoa repens, Pityopsis graminifolia var. graminifolia, Xyris, Andropogon, and Sporobolus floridanus.[3]
Liatris gracilis is frequent and abundant in the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[4]
Phenology
L. gracilis has been observed flowering in January and July through November, while fruiting has been observed in September through November.[3][5]
Seed dispersal
This species is thought to be dispersed by wind.[6]
Fire ecology
Liatris gracilis occurs in habitat that is maintained by frequent or annual fire,[3] and has been known to persist through repeated annual burns.[7]
Pollination
L. gracilis is a nectar producing plant that is attractive to native pollinators such as bees and butterflies. Songbirds across the longleaf forest will eat the seeds of Slender Blazing Star.[8]
