How about what I think is called Crape Jasmine in the US? Here it is called Clave de la India but it is Tabernaemontana divaricata. They can grow into a small tree here but also can be pruned as a shrub. I have a medium sized one in a large pot on a terrace that gets sun only for a few hours in the afternoon most of the year, it does get a lot of light other than that however. I have seen them in the ground in full sun to no sun but bright light. The smell is wonderful at night, especially if it is humid. Mine blooms pretty much year around, I've had some yellowing problems but they are getting better. I don't think it was getting enough water but I now have it on the irrigation system and the leaves are greening up, even with the yellowing leaves it was full of blooms.
