About Viola primulifolia L.
Viola primulifolia, commonly known as the primrose-leaf violet, is a species of flowering plant in the violet family. It is native to eastern North America, and may also be native to the Pacific Northwest. Its natural habitat consists of wet, acidic areas that are typically at least semi-open. It is a low, stemless perennial that produces white flowers in the spring. It can be told apart from the similar-looking species Viola lanceolata and Viola blanda by its ovate leaves, which have rounded to truncate bases and are 1.5 to 2 times as long as they are wide. While the typical form of Viola primulifolia grows across a large area of eastern North America, one variety of the species, named V. primulifolia var. occidentalis, grows in a small area of the Klamath Mountains in northwestern California and southwestern Oregon. These rare, highly localized populations have also alternatively been classified as Viola lanceolata ssp. occidentalis.
