Fragrant house plants

Any ideas for plants that will be happy in a pot in a south east facing window, that is nice and fragrant. Extra points if it releases its fragrance at night, but day fragrance is still good, especially if it lingers.

This is to go in my bedroom window, so a fragrance conducive to pleasant sleep is a bonus

 

You will struggle to get much in bloom all year round. I have a Hoya in our bedroom which fits the bill on and off throughout the year (except in the very short days of winter).

 

Jasmine?

 

Dormia nytolensis?

 

Stephanotis?
