The difference between Viola and Viola yedoensis

1. The difference of flowers:

The color of violet flowers is lighter, revealing a pink and purple appearance. The petals are symmetrical, mostly axially symmetrical. The flowering period is as early as April, and the edge of the calyx under the flower is arranged with tooth-like cuts.

The flowers of Viola yedoensis are dark in color, dark purple or bluish purple. The petals are not symmetrical and the flowering period is later than the former, blooming approximately after the violet flowers have faded. The edges of the calyx are relatively rounded and smooth or truncated.

2. The difference of leaves:

The petiole of the former is very long without narrow wings, 1-4.5 cm long, and a bit heart-shaped in shape.

The latter has longer leaves and petioles that appear shorter and narrowly winged.
