Describe symbolism in The Romance of the Rose by Guillaume De Lorris

The rose has been (and still is) a symbol of love, romance, and sexuality from the earliest days of history. This flower is sacred to Venus and is prized for its scent and beauty. The Biblical Song of Solomon also uses the metaphor of the "Rose of Sharon" to symbolize the Beloved (the woman.) Even today, red roses are among the most "romantic" of flowers, with the gift of a single red rose being especially significant. Possibly, the modern significance of the rose is a legacy of this work, and a mark of The Romance of the Rose's importance in Western literature, symbolism, and thought.

The rose does not symbolize the lady herself. Instead it symbolizes her love.
