Here're some photos to show off. Wish I could share also the fragrance, too. Really liked it when my small living was filled with the scent.
At 4.30 pm
At 6.30pm, the bloom opened a little
At 7.00 pm, the scent started to fill the air
At late at 10pm, the blooms still looked good
A pure, milky white
There was something unusual about this plant as, unlike the common "drooping" sight the morning-after, this was what I saw then - the two "faded" blooms looked like they would re-open the next evening.
Didn't look at all spent!
Unfortunately, I wouldn't be around then to confirm the fact.
Do you know of any species having this particular blooming/fading habit?
