Hard to tell, but it appears to be a swamp mallow.

Here is a link that might be useful: Swamp Mallow

That's a pretty one. I did a Google search on hardy hibiscus pink
And selected images.
When you click on a picture it usually tells the source.
"Summer Storm" comes close, but foliage is really purple.

Just get up the nerve and knock on the door and ask. Gardeners love to hear
Someone admires their plants. You might be offered a cutting. Seeds might be OK,
But what grows might not be true to original.

Thank you very much for the help. It surely looks like the Summer storm!

Brown, Also check the post. Kopper King. On this forum. I think that one has been avaiable a little longer. Looks very similar to your picture.
