Here are some of the meanings I found:
Giving a woman a columbine flower is considered bad luck, as they are a symbol of foolishness. Known to have five petals in the wild, the columbine flower was said to relate to foolishness because of its physical resemblance to a jester's five-pronged cap.
Innocence and the Holy Spirit
The columbine flower is also symbol of innocence. The fallen spurs of the columbine flower resemble the Virgin Mary's shoes, which were worn on her visits to see Elizabeth. According to legend, Mary's shoes caused the columbine flower to spring up beneath her, symbolizing her innocence. The fallen petals also resembled tiny doves, which are a symbol of the Holy Spirit, and the seven petals of the cultivated columbine flower represent the Holy Spirit's seven gifts.
