About

Viola adunca is a species of violet known by the common names hookedspur violet, early blue violet, sand violet, and western dog violet. It is native to meadows and forests of western North America, Canada, and the northern contiguous United States.

Where it grows

Viola adunca is the larval host plant of Myrtle's silverspot. Bees and other insects pollinate it. Polites mardon uses it as a nectar source, and birds and mice use the seed as a food source.

Uses

The leaves and flowers are edible, and can be eaten in salads, as potherbs, or brewed as tea. These plant parts are high in vitamins A and C. However, the rhizomes, fruit, and seeds are poisonous to humans and can cause upset stomach, intestinal problems, respiratory and circulatory depression.
