Is the flower represented by Lin Daiyu in a Dream of Red Mansions water hibiscus or wood hibiscus?

< < > Lin Daiyu and Qingwen are both compared to hibiscus.

There is a saying that these are two kinds of flowers.

Daiyu is the owner of water hibiscus, that is, lotus flower, because Daiyu's signboard "wind dew and clear sorrow" really refers to lotus flower, and the only flower that can compete with Baochai's peony is lotus flower.

Qingwen's owner is hibiscus mutabilis, also known as Manglietia, a shrub that blooms in autumn. Baoyu read "Daughter of Hibiscus" under the hibiscus tree.

Both of them wrote in hibiscus white, "Sunny is a shadow."
