The non flowering of Corydalis Africana may be influenced by light. If the light is not enough, it will be difficult for African Viola to bloom.
In the cultivation of Corydalis Africana, although appropriate nitrogen fertilizer is needed, if too much nitrogen fertilizer is applied during the growth period, the branches and leaves will grow luxuriantly, but it is difficult to blossom.
When breeding Corydalis Africana, reasonable light can make it bloom better, so we must control the light. In winter, to meet the needs of Corydalis Africana for light, it can be placed near the windowsill that can contact with the sun, with bright scattered light as the best. Shade is needed in summer because it doesn't need too much light.
