During the day, most people are busy with their work/activities. Rarely do they notice the other fragrances around them that come from other flowers, unless they take the time. Jasmine, allows it scent to be carried on the night's breeze, soothing the souls, and calming nerves. It's also known as "Queen of the Night." Chinese medicine states: Jasmine is said to cool the blood, as they help reduce a fever, or cool an over heated person, from the sun.
Fact: "Night flowering jasmine is not a true jasmine, it's actually Cestrum nocturnum which is in the nightshade family along with tobacco and tomatoes and a bunch of other plants."

Its ecological niche is to use scent to attract birds and insects at night when its lack of color means nothing.
8/23/05: Lost one of the 2 plants and purchased 3 more on-line which have grown to about 4 feet tall in a large pot. Just started to bloom a few nights ago and the other night we sat very close to enjoy the lovely sweet fragrance when to our surprise a baby hummingbird no more than 1/2" long came to visit and actually stayed for about a half hour. He even brushed against my arm and seemed to be intoxicated by the nectar.

Like scented stars appearing in the evening dusk, the night-blooming jasmine silently opens her five-petalled blossoms beneath our windows. In the dawn her sister will bloom, again filling the breeze with enchantment. Together, the jasmine sambac (night-blooming) and the jasmine grandiflorum (dawn-blooming) are among the most potent, ethereal, and intoxicating floral fragrances in the world.

Blomming in plants depends on the proportion of day and night. The answer is found in a chemical, called phytochrome, produced by plants. Phytochrome changes form when red light shines on it, and slowly changes back to its original form when it is in the dark. The plant "counts" the hours of darkness by how much of the phytochrome has changed back to its dark form before it is changed again by light. The chemical's reaction to light is very fast, so that even a short burst of light may turn all the plant's phytochrome back to the light form, and the plant will start all over again timing how long the night is.
The Jasmine is under category "SHORT-DAY WINTER-BLOOMERS" it requires at least 6 weeks of 55F nights and also the short-light autumn days to set their blooms

It can sense when the heat is off of it, letting it know bugs won't get near due to the dark and it's safer for it then

Because of internal phytohormone which direct its blooming at night

its b-l-o-o-m, honey. and i dont really know, but probobly its because the temperature cools down... or maybe the rays from the sun during the day are too powerful to let it grow so when its dark they dont have any obstacles to over come.
maybe

because the fragrance produced by its flowers attracts moths and other noctural polinators
