The Viola lanceolata, commonly known as Lance-leaved violet or White bog violet, is a small group of stemless white-flowered violets. It is an ornamental plant in the Violaceae family, part of the genus Viola. It gets its name from its lanceolate leaf shape and from the habitats in which it thrives.
Habitat and ecology
Viola lanceolata can be found growing in bogs, swamps, wet meadows and along shores in sandy soil. It is a perennial plant that blooms between May and June. Viola lanceolata frequently hybridizes with Northern White Violet, Viola macloskeyi, to form Primrose-leaved Violet Viola primulifolia. It grows in similar habitats but has leaves intermediate between lance shaped and the typical heart-shaped violet leaves of Northern White Violet.
The overall plant is 10–15 cm tall and has narrow, lance-shaped leaves. These leaves are sometimes wider in the summer than in the spring and have generally smooth surfaces. Its stem is smooth and slender. Its flower contain 5 white pedals located at the top of the stalk. The bottom three petals typically have purple veins. This plant spreads with root-like structures that grow over the surface of the ground (stolons). Its growth habit is a forb/herb.
