Taxonomic notes
Synonym: Salvia pitcheri Torrey ex Bentham
Subspecies: Salvia azurea Michaux ex Lamarck ssp. pitcheri (Torrey ex Bentham) Epling
Variety: Salvia azurea Michaux ex Lamarck var. grandiflora Bentham; Salvia azurea Michaux ex Lamarck var. azurea
Description
Azurea means "sky blue" referring to the color of the flower; however, some individuals may have white colored flowers.[1] The corolla is typically white or white with blue tint near the petal tips in northern Florida and southern Georgia (KMR).
"Perennial, [or annual] herbs [or shrubs], with erect to ascending quadrangular stems. Leaves toothed or lobed. Inflorescent a thryse, cymules 3-15 flowered. Calyx zygomorphic, 2-lipped; corolla zygomorphic, 2-lipped, blue to violet or red, rarely white. Fertile stamens 2, exserted, sterile stamens present or absent; stigma unequally 2-cleft, exserted."[2]
"Stems 0.7-1.5 m tall, 1-several from a crown, leafy simple or branched above, basal leaves absent. Leaves linear, narrowly elliptic to elliptic-lanceolate, 4-8.5 cm long, 0.3-3 cm wide, acute to obtuse, entire to crenate-serrate, base cuneate to attenuate, petioles obscured by decurrent blade. Calyx 5-8 mm long, upper lip entire, lower 2-toothed, teeth acute, not bristle tipped; corolla blue, 1.3-1.5 cm long; the 2 locules of each anther side by side. Mericarps olive-brown, resinous-glandular, dull, ellipsoid to obovoid, 2.3-2.8 mm long."[2]
Distribution
In Kansas, it is found abundantly as a native tallgrass prairie perennial.[3]
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. azurea can be found in upland pinewoods, burned longleaf pine habitats, sandhills, sandy slopes, flatwoods, pine-oak-hickory woods, and mesic longleaf pine-wiregrass woods.[4][1] it can also grow in open slopes of power line corridors. It has been recorded to grow in moist sandy loam.[4] In south Georgia upland pines, it is restricted to native groundcover.[5]
Associated species include longleaf pine, oak species, and wiregrass.[4]
S. azurea reduced its occurrence in response to soil disturbance by agriculture in South Carolina longleaf woodlands.[6] It has shown resistance to regrowth in reestablished longleaf pine woodlands that were disturbed by agricultural practices, making it a possible indicator species for remnant woodlands.[7] Similarly, this species has become absent or decreased its occurrence in response to agriculture in southwest Georgia pinelands.[5]
Salvia azurea is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[8]
Phenology
This species has been observed to flower from September to November.[1][9] Kevin Robertson has observed this species flower within three months of burning. KMR
Fire ecology
Populations of Salvia azurea have been known to persist through repeated annual burns.[10][11]
Herbivory and toxicology
In general (after experimenting the effects of bison and cattle on growth, reproduction, and abundances of Salvia azurea and other perennials), bison resulted in greater plant biomass and height, and lower number of stems per plant relative to plants in ungrazed sites, whereas cattle resulted in lower plant biomass, plant height, and number of stems per plant.[3]
Conservation, cultivation, and restoration
S. azurea should avoid soil disturbance by agriculture to preserve its presence in pine communities.[5][6][7]
