I do not know of any indoor plants that have a fragrance, unless you attempt to grow herbs indoors (unfortunately, I don't think most herbs do well inside).
With respect to flowers, I can only think of a couple. Select Sansevieria (I don't believe all Sansevieria flowers have a fragrance) can have fragrance. I know that the 'Corn Plant' (Dracaena fragrans) is said to have an overwhelming scent when it blooms, but... from what it sounds like, it takes many years before it will bloom. I think the same holds true for Sansevieria, in that it's not a super common occurrence to see one bloom indoors. Certain orchids have smells, but I can't recall which ones and some Orchids are not recommended for the "beginner." Well, I'm not a beginner myself, but that's one of those plants I can't grow (but, the next person grows them like weeds!).
