Description
P. floridana is an herbaceous plant with an erect stem. Its leaves are lanceolate to linear. The leaves are largest below the middle of the stem and the upper leaves are opposite or subopposite. The cymes open, with the lowest branches elongate and less than 1 cm long. The sepals are awned, with the awn being 0.5-3.0 mm long. The corolla is usually glandular-pubescent or pilose (rarely glabrous), and colored blue, lavender, or pink. The pedicels are 1-8 mm long.[1]
Distribution
P. floridana ranges from southwest Georgia and southeast Alabama, south to Florida Panhandle and northwest peninsular Florida.[1]
Ecology
Habitat
P. floridana has been documented to occur on a sandy ridge in a longleaf pine/scrub-oak woodland; pine/hardwood forest; open piney areas; sandy soil of open pine flatwoods; amongst grasses in a burned longleaf pine forest; along the edge of pine-oak-hickory woods; semi-boggy slope of longleaf pine savanna; and an annually burned pine savanna. It has been observed to grow on sandy roadsides, picnic areas, dry sand and gravel in an old field, cut and burned over pine flatwoods, and along a powerline corridor.[2] Soils observed include sand, dry sandy loam, drying loamy sand, and in shaded loose loamy sand.[2] Associated species include Pinus palustris, Tetragonotheca, Onosmodium, Pediomelum, Quercus laurifolia, Quercus margarettae, Quercus incana, Quercus laevis, Vaccinium arboreum, Vaccinium stamineum, Opuntia humifusa and Asclepias.[2]
Phlox floridana is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[3]
Phenology
P. floridana has been observed flowering April through November with peak inflorescence in May[2][4]. It has been observed to resprout and flower within three months of being burned.[5]
Seed dispersal
This species is thought to be dispersed by wind.[6]
Fire ecology
It flowers within two months of burning in early summer. KMR
