Mimosa is a large genus containing many species. It's also a common name used for some related species like Albizia julibrissin. If I had to guess, I'd bet Albizia julibrissin is what you actually have. Take a look at the link below and see if that's what you have.
Here is a link that might be useful: National Park Service Factsheet
