@aramy699, are you sure it has no scent, as Jasminum sambac is highly scented as all this genus are ?
Yes - maybe it is the Tabernaemontana instead. However this says the double form of that one is fragrant also - if this is correct or non varying then the question of aramy not getting any smell out of their plant remains unresolved: Tabernaemontana divaricata - Wikipedia
