Once the cab driver was stuck on the road with his wagon, where the wine was, so much that he could not move it despite all his efforts. Just passing by the Mother of God. Seeing the vain attempts of the poor man, and deciding to try it, she turned to the one with the words: "I'm tired and thirsty, pour me a glass of wine, and then I'll help free your cart." "Willingly," answered the cabman, "but I do not have a glass where you can pour." Then the Virgin tore off a white flower with pink stripes, which is called a field bindweed and looks a bit like a glass, and handed it to the cabman. He filled the flower with wine, The Virgin drank, and at the same moment the cart was freed, and the poor man could move on. Since then, these flowers are also called "glasses of the Mother of God."
