I’ve been learning a little about the Confederate rose hibiscus tonight. What a neat plant! Walter’s site has a few previous post regarding that plant. Just type it into the search box at upper right. Here is one of the links http://www.walterreeves.com/gardening-q-and-a/confederate-rose/
Confederate Rose seems to be a double bloom variety. Yours may be another hibiscus. That’s ok. I’ve never met one I didn’t love!
I think Russell is correct except for common name. The pictured plant is indeed swamp mallow….but the name Confederate rose is what most folks use to refer to Hibiscus mutabilis, not Hibiscus moscheutos.
