I know absolutely nothing about hibiscus, but have been trying to learn on this forum. My daughter gave me one that was dying in her greenhouse. She did not know the type. She did say it has a large pink bloom (like dinnerplate size.) I wonder if it is the Moy hibiscus and/or the hardy one. Any suggestions?

If it is the hardy one, is it too late to plant outdoors or should I bring it in this winter, since I am still nursing it along? It was covered in scale, which I was able to control. But its leaves are still yellowed, even though I gave it some fertilizer. It does have some new leaves, but they are yellow/green too.

I know without seeing the plant it is hard for you to tell, but I am searching for any ideas on where to go from here. I have never seen the bloom, but I have had it only since August. I'm just trying to salvage it, since my daughter had faith that I could! Thanks for your input.
