That white one has huge blooms for a pel and is usually covered in blooms so it makes a good impact so some of these single ones, depending one the size of the blooms, are real good. In fact almost all the ones in my Germany photos are single blooms. They are clustered at the ends of the stems to really be showy.
I don't think I have ever seen hummers on these, they usually go for my fuchsias and any tube/bell like blooms.
