Canadian white violet
All the western states except California and Nevada. Less common in the Pacific Northwest
Between 4 and 16 inches
Moist, wooded locations
Cordate, stalked, up to 4 inches long, with toothed margins and a slightly rough surface
The pretty white flowers of viola canadensis have two upper petals, curved slightly backwards, two side petals and one broader lower petal. All are yellow at the base, the lowest 3 have a few parallel purple lines also at the base, while the lower surface of the side petals has a group of short, thick hairs. Underneath are five smaller, light green sepals and a nectar spur. The undersides of the petals have a pinkish tinge. Flowers are about 3/4 of an inch in diameter and produced in small numbers (only a few are in bloom at any one time), so they are relatively inconspicuous compared to the large green, heart-shaped leaves, which grow in abundance along the lower stems. Flowers point downwards, and grow from the upper leaf axils.
