| Author | (Lakela) Nesom | |
| Distribution | This is a newly described species, in 2021. Throughout the southwestern third to half of the Mountains, north and east to Haywood, Buncombe, and Polk counties (Nesom 2022). Western Carolina University Herbarium lists a collection on SERNEC for Caldwell County, farther north than reported by Nesom (2022); this specimen might need confirmation. The many photos on iNaturalist listed for this species cannot reasonably be judged for correctness of identification and are not included here.
"S. Blue Ridge of sw. NC, se. TN, nw. SC, ne. GA; disjunct slightly westwards in sc. TN and n. AL" (Weakley 2022).

| Abundance | Apparently fairly common to common, at least locally. | |
| Habitat | Rich hardwood forests, cove forests, and similar hardwood forests. Note that habitat distinctions among the four species of Tiarella in NC have not been described, as Weakley's (2024) habitat listings are identical for all four (for now). | |
| Phenology | All Tiarella species flower and fruit from April into June. | |
| Identification | See T. cordifolia for the general description. There are two stoloniferous Tiarella species in NC, and this one has "Leaves usually with acute-acuminate lobes, terminal lobe prominently extended; flowering stem usually with 1–2 leaves or foliaceous bracts; sepals 1.5-2 mm long", versus "Leaves usually with obtuse to rounded lobes, terminal lobe not prominently extended; flowering stem very rarely with a small bract; sepals 2.5-3.5 mm long" for the newly-described T. stolonifera. Note that the newly defined T. cordifolia lacks herbaceous, leafy stolons (runners); it has a clumped look to the plants. | |
| Taxonomic Comments | Nesom (2021) described this and several other new species of Tiarella.
