Here is a closer shot, earlier in the day, some of the leaves still have dew on them. so pretty.

Sunni, it would be difficult to ID a particular cultivar by name. It is one of the Hardy Hibiscus, not Tropical. I'm not even sure which species hardy Hibiscus you have. The link below is very informative and may help you with an ID.

You can also do a Google Images search for "pink hardy hibiscus" and spend an enjoyable morning, browsing all the lucious pictures. :-)

One of the more experienced members will probably chime in with better information for you.

Sunnibeach4,
This is a Hibiscus Moscheutos. 'Luna Rose' might be a candidate, but I suspect it could be a Fleming Hibiscus. Either way, it will produce flowers year after year. Water often, and read about the simple care they need. Each winter they die back and emerge late spring to early summer.

It appears to me to be a Swamp Rose Mallow. They come in different colors (and are referred to by different names).
