I love abutilon and the giant hardy hibiscus blooms. We've gotten hooked on the Cajun hibiscus in the last year or so. They come in some beautiful colors but you really have to battle the bugs for them here. It seems like they're everything's favorite meal.
Did you find the sea grape? I think they're pretty with the big leathery leaves and the red veining. I have a few seeds that I picked up in Florida if you want to try to grow one. I'd be glad to send some to you.
