Conradina verticillata
Also called Cumberland Rosemary
Conradina verticillata is a flowering shrub in the mint family, found in the Cumberland Plateau. It is also called Conradina montana, Cumberland rosemary or Cumberland false rosemary. It has been classified as a threatened species under the Endangered Species Act since 1991.
Cumberland rosemary lives on the rocky river banks of the Cumberland Plateau. It grows best in full sunlight and in well-drained soil with no visible organic matter. The soil may be mostly sand, or sand mixed with gravel. Thus, it also benefits from topographic features which enhance sand deposition. It relies on periodic flooding to eliminate taller plants which might leave Cumberland rosemary in the shade. Extended flooding may induce rooting at the lower stem nodes and disperse seeds and viable plant fragments downstream. It has been hypothesized Cumberland rosemary may thrive with alternating floods and extreme droughts, as this regime helps eliminate competition, but data is lacking on this.
