This is a newly described species, described by Nesom in 2021. Read more at Vascular Plants of North Carolina.
Five species of Tiarella are present in the eastern United States! The main features distinguishing them are presence/absence of stolons, shape of the basal leaves, and presence/absence of leaves on the flowering stem. When the plants are sorted by these physical characters, the five entities are remarkably consistent in geography, showing sharp boundaries with very little overlap. Each of the five tiarellas fits the generally understood definition of “species” – a population system distinct in appearance from others and genetically discrete, forming few or no hybrids with other population systems. Read more in New Species of Foamflower (Nesom, 2022).
