Hmmmm just discovered this thread while surfing around. Stuff below has not been mentioned.
Heliotrope not mentioned here. Have a white one as an indoor plant and it has been in constant bloom since August 2014. Wonderful vanilla like scent. I plant Marine Heliotrope outdoors.
Brunfelsia - any of them. I have a Yesterday, Today and Tomorrow that has been in almost constant bloom since June 2014. Lady of the night is awesome as well and has lovely blooms. Princess of the night for over a year yet to bloom.
Cashmere Bouquet (Clerodendrum philippinum) - a soft smell
White Butterfly Ginger - yum
Buddleia - Butterfly Bush - very subtle. When you have several ( I have ~ 25) a nice scent. Even massed - not overwhelming.
Datura (NOID Cream Triple) - must get up early or stay up late
Oleander roseum - very subtle - smells just like an old fashioned rose
Peruvian Daffodil - gentle, sweet - a wild bloom
Species Daffodil

Brugmansia - mine (3) are blooming in my basement grow area - when I walked in the house the other day from outside, the smell was wonderful.
