Kadereit (volume editor). The Families and Genera of Vascular Plants volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. Its common name is false rosemary, or rarely, short leaf rosemary. There are 7 species of Conradina, all native to the southeastern United States.Christine E. Edwards, Walter S. Judd, Gretchen M. Ionta, and Brenda Herring. 2009. "Using Population Genetic Data as a Tool to Identify New Species: Conradina cygniflora (Lamiaceae), a New, Endangered Species from Florida". Systematic Botany 34(4):747-759. Conradina verticillata grows on the Cumberland Plateau in Kentucky and Tennessee.Alan S. Weakley. "Conradina" pages 745-746. In: Flora of the Carolinas, Virginia, and Georgia (title varying with update). (see External links below). The other five grow mainly in Florida. All of the species are closely related and there is some doubt about whether they are all separate. Most species occupy xeric with well-drained composed of white sand. The genus Conradina was established by Asa Gray in 1870.Asa Gray. 1870. Proceedings of the American Academy of Arts and Sciences 8:294. It was named for the American botanist Solomon White Conrad.Umberto Quattrocchi. 2000. CRC World Dictionary of Plant Names volume I. CRC Press: Boca Raton; New York; Washington, DC;, USA. London, UK.

False rosemary is adapted to and open, Shrubland areas. It is a Woody plant Perennial plant shrub, often with masses of white to lavender blooms in the early spring or fall. These blooms attract several species of . Conradina often has a scrubby appearance; however some plants seem to have a denser habitus. Conradina is found growing in association with Pinus clausa and , and may be a pioneer species in disturbed areas. Terpenes released from false rosemary are allelopathic, and suppresses the growth of grasses. This is thought to help prevent wildfires. The plants are commonly up to in height.
False rosemary has been suggested as a landscaping plant for xeriscaping because it is drought tolerant and grows well with little water, even in poor soils.
False rosemary has flowers and scent similar to those of Rosmarinus officinalis.
Until recently, limited scientific study had been published on culinary herb, medicinal or other properties of Conradina, but it has been shown to be a potential source for numerous and other compounds.Brian P. Quinn, Ulrich R. Bernier, and Matthew M. Booth. 2007. "Identification of compounds from Etonia rosemary (Conradina etonia)". Journal of Chromatography A 1160(2007):306–310.

Apart from Conradina verticillata, which is a triploid,USFWS. Conradina verticillata (Cumberland Rosemary) determined to be threatened. Federal Register November 29, 1991. all of the species of Conradina are diploid and have a haploid Ploidy of 12. Conradina has been the subject of Genetics research.Home Page of Christine E. Edwards.
