If you too are curious of the saying “Forget-me-not”.
“Forget-me-not, O Lord!” is what a poor German knight shouted as he fell into a river. He and his lady were picking flowers by the side of the river at the time, no doubt enjoying the beautiful day around them, and yet as fate would have it, the knight’s armour dragged him down to the bottom as he fell in. Upon his cries to the Lord, he threw the blue posy of flowers to his loved one and promptly drowned. This little tale reportedly dates to around the 15th century, but no doubt had different permeations along the way, as romantic stories often do. Hence, the concept of remembrance, eternal love and faithfulness grow from this.” – : http://artofmourning.com
