Night blooming jasmine. Easy to grow, just cut back after it blooms. It is without doubt noticed at night when in bloom..Good Luck

Sweet Almond

You can grow both moon vine and morning glory in your zones. Mon vines require at leat half a day of direct sunlight and both plants can become invasive. Moon vines are known for self seeding so one of the ways to contain them is to dead head them. I am enclosing a link that lists plants, vines, etc that are either fragrant in bloom or the foliage. You will notice a N S or C which is the indication of the part of the state where the plant will thrive. It never hurts to experiment with some that are on the border of your zone as micro0climates can be found everywhere. Disney is the classic example of micro climates abd griwubg plant that would die eosewhere. Have fun experimenting and I do adore fragrant plants, thus the screen name. Linda

I swear I answered this before, but somehow it's gone. Anyway, sweet almond is my favorite too. It can be a shrub or a tree. If you grow it as a shrub leave enough space as it is very wide. I've got mine as a 12ft tree right by the back door. :o)
