According to Greek mythology, a young man named Leander fell deeply in love with Lady Love. He swam the Hellespont every night to see his beloved.

Unfortunately, one night he was drowned in his attempt and the crashing waves threw his body against sharp rocks. His lover found him as she walked the shores calling “Oh Leander, Oh Leander.” Finally, she found the beautiful flower clutched in his hand. She took the flower and kept it as a symbol of their everlasting love. She planted it and called it – Oleander.
