Yup, Tiffany this particular white one is Begonia odorata alba, and has a nice fresh scent in the mornings as it's warming up. The plant is vigorous and also will stand some sun. It's a sprawler, though, so I've seen it planted behind a row of low shrubs, and laying up over the shrubs in front for support. I have it in a huge 20in. hanging basket that needs to come down and be re-planted this year after about 3 years. The flower umbels are up to 10in across, and it has big, roundish dark green leaves too.

This year it is twice the size, scraggly and I've been taking a lot of cuttings preparing for making a whole new basket.
