The night blooming jasmine is full of greenish white blossoms which open in the night and waft their strong scent across. This shrub is leanining from my neighbour's garden into mine. The strong perfume gives me an equally strong headache. Luckily my bedroom is on the far side of the house and so I can sleep peacefully. Curiously enough, the strong perfume stops emanating at day break, although the flowers are still open. It is as though the flowers have stoppered their scent bottles at once!
Fortunately for me, this monsoons the abundant flowers have not opened their perfume sachets even in the night because of the unusually dry weather.
