The flowers have bloomed in my army camp. Maybe the quick transitions between the blazing sun and the pouring rain serve as signals for the jasmine flowers to bloom together, thereby improving their chances of successful cross-pollenation. Whatever the reason, it remains a fact that there was a huge bloom of Jasmine flowers in my camp, and it's really fragrant. Since young I have always been told that flowers are fragrant, but I never actually associated flowers with fragrance because all the flowers I've seen (i.e. bougainvilla, ixora, hibiscus) have no smell.

Yes, so if you wish to make your house fragrant naturally, plant jasmine. You can't really smell many other flowers.

Only if you are prepared to have them visited by bees though. The jasmine bloom in my camp received good patronage from them.
