| Distribution | Throughout the Mountains, and a few foothills ranges like the South Mountains. Sparingly east to Durham and Lee counties, in the eastern Piedmont.
This is a mostly Northern and Great Lakes species, ranging south mostly in the Appalachians to AL, and scattered into the Piedmont. | |
| Abundance | Common in the Mountains; infrequent into the western Piedmont, and very rare to rare farther to the east in the Piedmont. The Lee population was rediscovered in 2021 on rich slopes facing the Deep River. | |
| Habitat | This is a species of rich hardwood forests, usually on slopes but also on floodplains. It is most common in Rich Cove Forests. Another toothwort, C. concatenata, also grows in similar habitats, often in slightly richer (more circumneutral) soil. |
| Phenology | Blooms in April and May, and fruits in May and June, but in this species the basal leaves are almost evergreen. | |
| Identification | Of the four "toothworts" in the state (formerly Dentaria), this is the most robust and a bit taller than the others (angustata, concatenata, and dissecta), growing to an average of 12 inches tall. The several basal leave are tripartite, with each of the 3 leaflets being elliptical with rounded teeth, averaging about 3 inches long and half as wide, with petioles often 4-5 inches long. The two stem leaves are nearly opposite and somewhat similar to the basal leaves, with 3 leaflets that are ovate to elliptic. The flower cluster is very similar to the other three species, white but fade to pinkish, and each flower is about 3/4-inch long or across. All other similar species have narrower stem leaflets. This is usually an easily seen species of cove forests in the Mountains, typically seen on spring wildflower walks. | |
| Taxonomic Comments | Formerly was included in the genus Dentaria by some references.
