''Conradina'' is a genus of flowering plants in the mint family, Lamiaceae.〔Raymond M. Harley, Sandy Atkins, Andrey L. Budantsev, Philip D. Cantino, Barry J. Conn, Renée J. Grayer, Madeline M. Harley, Rogier P.J. de Kok, Tatyana V. Krestovskaja, Ramón Morales, Alan J. Paton, and P. Olof Ryding. 2004. "Labiatae" pages 167-275. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. ISBN 978-3-540-40593-1〕 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 habitats with well-drained soils 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. ISBN 978-0-8493-2675-2 (vol. I). (see ''External links'' below).〕 False Rosemary is adapted to dunes and open, scrubby areas. It is a woody perennial shrub, often with masses of white to lavender blooms in the early spring or fall. These blooms attract several species of bees. ''Conradina'' often has a scrubby appearance; however some plants seem to have a denser habitus. ''Conradina'' is found growing in association with sand pines and oaks, 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, medicinal or other properties of ''Conradina'', but it has been shown to be a potential source for numerous essential oils 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. (see ''External links'' below).〕 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 chromosome number of 12. ''Conradina'' has been the subject of genetic research.〔Home Page of Christine E. Edwards. (see ''External links'' below).〕 ==Species== * ''Conradina brevifolia'' - Shortleaf False Rosemary. This species grows in Polk and Highlands counties on the Lake Wales Ridge in Central peninsular Florida. It is listed as federally endangered species. * ''Conradina cygniflora'' - described in 2009, known only from Putnam County, Florida. * ''Conradina grandiflora'' - Largeflower False Rosemary. This species grows in counties along the Atlantic coast of Florida. It is listed as a threatened species in the state of Florida. * ''Conradina canescens'' - False Rosemary. This species is found along the gulf coast of Mississippi, Alabama and Florida, as well as in the sand hills of central Florida.〔 It is the most common and widespread species in the genus. * ''Conradina etonia'' - Etonia Rosemary.
