@ DaisyI; thans for the link, yes that is the same plant on that page, how ever they did not mention the species name there.
Thank you islander. Sorry I do not think it is T tiliaceum. Stem, petoles and leaves are fuzzy, bit prickly. Flowers do look like sea hibiscus, but never changes color to brownish. Never see this plant on low land, and they never take shapes into trees, just shrub (sorry for lacking this information on previous post)
Btw, a friend suggest it might be wild type of Abelmoschus moschatus
