I think all the orientals are fragant. Orienpets, less so. What zone are you in? Orientals can be harder to grow. I live in the midwest, and here they peter out after a few years. Orienpets are much easier to grow, but I think most don't have the heady scent of the orientals. It's there, but it's lighter. I don't grow them for fragrance so I have not paid strict attention to which varieties have a stronger scent. I know I can't bring cut orientals in the house because my husband says the scent is too overwhelming.

Trumpets also have a good scent. I don't grow enough to recommend them across the board, as being universally scented. I have one called "Pink Perfection" or "Pink Palace." I was walking around the front yard in early July last year, and smelled something wonderful. It took me a while to figure out that it was that lily. It was a different scent than the orientals (I have no orientals in front). I enjoyed it the whole time it bloomed. It could be detected at least 10 feet away, more depending on which way the wind was blowing.
