How did the forget-me-not get its name?

Legend has it that in medieval times, a knight and his lady were walking along the side of a river. He picked a posy of flowers, but because of the weight of his armour he fell into the river. As he was drowning he threw the posy to his loved one and shouted "Forget-me-not." It was often worn by ladies as a sign of faithfulness and enduring love.
