I grow this plant in a large container. I grew it in Austin (8b) and now have it in Houston in (9b). My experience is that it needs a good bit of shade in a hot climate. It will also wilt pretty quickly if it gets dry. It did well until mid summer, then pouted a bit. Now that the temperature has gone down a little, it is putting out new growth and blooms. I expect it will have a good fall season.
