Characteristics:

Long-spurred violet is a perennial with short to long, slender rhizomes from which the stems arise. The stems are leafy, short at first, but elongating as the season progresses to 10 cm. The herbage may be smooth to densely short-hairy. The leaf blades are 1-3 cm long, usually ovate cordate in shape, but may also be ovate-lanceolate to kidney-shaped with the tip tapering to a rounded point. The leaf surface may be brown-dotted and the margins have rounded teeth or may be entire. The leaf petioles are often longer than the blades, and range from 5-8 cm long.

The flowers range from 5-15 mm long with a long spur, slightly hooked at the end, which is slightly more than half the length of the lower petal. The 5 petals are blue to deep violet in color, with the lower 3 having a white base with purple-violet pencil marks in the throat.


Habitat:

Long-spurred may be found in dry to moist meadows, open woods, and open ground from near sea level to near timberline.


Range:

Long-spurred violet is a widespread species, being found over much of western North America and extending eastward to the Atlantic coast.
