I don't know much about hibiscus and I bought a nice tropical grafted one with huge orange flowers in a pot in the spring. I think you would call it a standard because it's got a trunk and you could see the graft unions where the graft was made at the top of the trunk.

Anyway, it got stressed by a cold draft and died quickly of spider mites, but then I noticed the understock was growing leaves of its own. I know it's not the same as the grafted one because the leaves are different. The new growth is doing well and I am now wondering what it will be. Is there a particular hibiscus that is commonly used as understock? Will it flower? Thanks for any advice.
