A single flower at the end of a naked stem that typically rises above the leaves. Flowers are white, about 1/3 inch wide, 5-petaled with purple streaks on the three lower petals. The lateral petals may be hairless or have a few sparse hairs at the base (bearded).
Leaves and stems:
The leaves are all basal, spear to egg-shaped, the blade twice as long as wide, up to 3¾ inches long and 2 inches wide, tapering to a dull point at the tip, nearly straight to slightly heart-shaped at the base, the upper stalk narrowly winged. Leaf edges are typically scalloped but may be nearly toothless. Leaves and stems are generally hairless throughout except for a few sparse, compressed hairs along the lower leaf veins and sometimes on the flower stem.
Primrose-leaved violet is easily distinguished from all other violets by its unique leaf shape from which it gets its common name. There has been some debate on its status as a unique species, some recognizing it as a stable, natural hybrid between Small White Violet (Viola macloskeyi) and Lance-leaved Violet (Viola lanceolata), often present where the other two species are found together. In Minnesota, that is primarily within the Anoka Sandplain. The other side of this debate says it is a unique species, supported by the fact that the true hybrid is (probably? usually?) sterile. It can go either way but we're siding with the unique species group until further studies say otherwise.
