It looks like Abelmoschus esculentus, AKA Okra.

It may also be Okra's close relative, Abelmoschus manihot, sweet hibiscus.

Thanks. A. manihot it seems to be. It's never set a pod, but it's only been blooming about a week. I'll have to check for seeds since it seems to be cold hardy only to zone 9.

Yes, a week is not nearly long enough.

See if you can successfully dig in the fall and bring indoors for the winter. You don't have much to loose in trying!
