Collinsonia verticillata is a species of flowering plant in the mint family known by the common names stoneroot, early stoneroot, whorled stoneroot, and whorled horse-balm. It is native to the United States, where it occurs in the southeastern states, especially the southern Appalachian Mountains, its distribution extending north to Ohio.[2]
This rhizomatous herb has two to three pairs of leaves and an unbranched inflorescence bearing white, pink, or lavender flowers, each with four stamens.[2]
The plant grows in rich soils in mountain forests. Besides this, very little is known about this species.[2]
