The violet is a pledge of faithfulness.
In his sonnets, Shakespeare used the violet as a symbol of humility and constancy in love.
As if shy, these rich dark flowers withdraw their color to the shadowy glade. “How they would lose their beauty,” wrote Keats, “were they to throng into the highway crying out, ‘Admire me—I am a violet.’”
A dream of violets was said to foretell an advancement in life.
