Origin/Distribution: The species is native from Ohio south to the Gulf of Mexico. This cultivar was selected from seedlings exhibiting much more silvery foliage than the species. It was introduced into commercial production by Mt. Cuba Center in 2010. 

Habitat: moist, deciduous woods

More: This lovely plant will make a dense ground cover with adequate moisture, however, it is adaptable to dry shade where the plants will remain in more discrete clumps. In the wild the species is found growing with Mayapple, Trilliums, and Partridgeberry. Some sources say hardy to zone 6, but others say zone 5. I will keep you posted. Viola flowers are edible. Good for a rock garden.
