How tough is this plant

My best friend is known to my boys as Meme. There is a hardy hibiscus by that name and we gave her one as a gift. She planted it near her deck and it was little, but doing fine. When her husband was doing dirt work to put in their new pool, he pretty much mangled the poor meme with a bobcat. She threatened him with his life, dug up the sad little nub of a plant with it's roots and put it in a container. That thing came back, bloomed, and now she is germinating it's seeds. Below the previous post is a picture of Rose Mallow, another hardy hibiscus. I don't have a picture of the meme, but it is a solid light pink with heart shaped leaves.
