DistributionPrimarily limited to the Piedmont, where it occurs in nearly all counties. Sparingly present into the upper Coastal Plain, in the northwestern portion -- east to Martin and Wilson counties. Sparingly in the edge of the mountains, probably close to the Blue Ridge Escarpment.

This is an Eastern species, ranging from southern NY and MO south to northern GA and OK.
AbundanceCommon over the entire Piedmont, but rare in the northwestern Coastal Plain. Infrequent in the extreme eastern edge of the mountains.
HabitatThis is a species of dry, often rocky, acidic soil, usually on sloping ground. It occurs in dry and usually rocky woods, bluffs, cliffs, and other shady to semi-shaded places with thin soil on slopes or ridges.

PhenologyBlooms from late August to September, and fruits from October to November.
IdentificationThis is the only species in the genus in the US, and thus is quite different from other species, being quite familiar to biologists working in the Piedmont. It is a rather low and "bushy" plant, to about 9-12" tall, with many branches from near the base, and quite slender but wiry and stiff/straight stems and branches. The paired opposite leaves are small and ovate to triangular, clasping, serrate, but only about 1.5" long and half as wide. They are very mint-scented when broken. In many of the upper leaf axils are clusters of small pink flowers, each about 1/3" long and narrow. A few stamens and the pistil extend beyond the corolla. As a general rule, identify this plant by its low and bushy look with numerous small triangular leaves, very fragrant when broken; and the many axillary clusters of small pink flowers.
