The flowers of Viola tricolor are much larger than those of Corydalis, generally 2-3 times larger than corydalis. The flowers of Corydalis are about 2-4cm, while the flowers of Corydalis tricolor are 4-12cm, and the size contrast is obvious. In addition, the flowers of Pansy are longer than others.
Pansy, as the name suggests, is generally composed of three colors: yellow, blue and black. There are black dots in the middle of the flowers, which are just like grimaces, extremely interesting. In addition, the flowers of many varieties of Pansy are usually black or dark, and also have all yellow. Corydalis, on the other hand, is light colored and has no dark dots in the middle, but has a straight black line like a cat's beard. To judge whether it is pansy or Corydalis, you can use the pattern in the middle of the flower. The one with black circle in the middle of the flower is pansy, and the one with black line in the middle is Corydalis.
Pansy, native to Iceland, has good cold resistance, but is not heat-resistant and poor growth in summer, so it is generally planted in autumn and blooms in spring. Corydalis originated in Europe, is more heat-resistant than Viola tricolor, and can bloom in early summer of autumn sowing or autumn of spring sowing. The growth period of Viola tricolor is 15-17 weeks, and that of Corydalis is 13-15 weeks.
