USDA Symbol: VIGL

USDA Native Status: L48 (N), AK (N), CAN (N)

This is a 4-8 in. violet with large, bright-green, heart-shaped basal leaves just below the deep-yellow, pansy-like flowers. The lateral and lower petals are marked with purple veins. Slender leaning or erect stems with leaves only in upper one-third, and bilaterally symmetrical, yellow flowers facing outward, hanging from slender stalks.

A very common species in moist, shaded places in woods. Most western Violets have yellow rather than purple corollas, but all have the perky little flower with a spur or pouch behind the lower petal. The lower petal forms a landing platform for insects seeking nectar within the spur.
