About Viola sempervirens Greene
Viola sempervirens Greene, commonly called redwood violet, is a perennial herb that reaches about 5 centimeters (2 inches) tall. Its simple, leathery leaves grow 1 to 3 centimeters (1 inch) long, are cordate-ovate in shape, and are basal, emerging from stems attached to the plant's base. Each plant produces a single flower that has five petals. The petals measure 5 to 15 millimeters (around 0.5 inches) long, and are bright yellow to gold in color; the three lower petals have red-purple streaks at their base. This species typically blooms between March and June.
