About Collinsonia verticillata Baldwin ex Elliott
Collinsonia verticillata is a species of flowering plant in the mint family. It has several common names: stoneroot, early stoneroot, whorled stoneroot, and whorled horse-balm. This species is native to the United States, occurring in southeastern states, particularly in the southern Appalachian Mountains. Its range extends northward into Ohio. It is a rhizomatous herb that produces two to three pairs of leaves, plus an unbranched inflorescence that holds white, pink, or lavender flowers; each individual flower has four stamens. The plant grows in rich soils within mountain forests, and very little additional information is known about this species.
