Dogtooth violet is not a violet but a true lily. The name comes from the shape of the bulb which resembles a dogs tooth. This is one of the earliest wildflowers, blooming in March here in Missouri. The single bloom forms a seed pod and the plants will self sow in time to increase their number.
A good companion to Dutchmen's breeches and gold star grass. The bulb should be planted vertically about an inch deep.
