Cumberland false rosemary

Cumberland false rosemary (Conradina verticillata)
Plant Botanical Name: 
Conradina verticillata

Conradina verticillata closely resembles culinary rosemary, but it is a species native to the southeastern United States and is increasingly threatened in the wild. Also known as Cumberland false rosemary, its few remaining populations in Kentucky and Tennessee are often trampled by hikers and nature lovers. Additional threats include development, mining, and illegal collecting. In its native habitat of well-drained sandbars and riverbanks, this plant is often associated with Chionathus, Itea, Marshallia grandiflora, Ropogon gerardii, and Aster linarifolius. Although federally listed, it relatively easy to cultivate and a wonderful native plant for southern rock gardens, as are its companions in nature.
