Bunga Bakawali in Bahasa Malaysia, but what is it called in English?

I tried many time searching and surfing for the name of the flower but with no avail. Maybe someone out there would come here one day with the name as this is what I’m hoping for.

A very lovely species, each flower only blooms once and starts blooming at late hours which is around 11 pm. It opens up almost as big as a plate and is white in color with sweet fragrance smell.  This flower does not last; it drooped immediately the next morning as the sun rise.

Brought home and planted by my mother during her younger years.  Mother really loved the flower.  I remember sitting with her at the verandah one late night waiting for the flower to bloom at midnight.  I could not make it though; I was already fast asleep when the flower bloomed.  I saw the bloom only from the picture mother took but of course it was in black and white.

Much, much later after that, I started my own flower garden.  Like my mother, I too love this flower.  I planted it in a large clay pot and placed it beside the staircase at the front.  Why there? So it would be easy for me to peep through the window without going out at late hours just to see it bloom. Can’t help imagining seeing something else…. ehh, scary!!

Again later, I saw the flowers sold in the market.  When I asked what it is for, the Chinese lady being the vendor said it is for cooking; normally they make soup out of it.  I did try making soup with the flower; it turned starchy and ****!!!, I just couldn’t take it.  But maybe next time I’ll consider cooking it with cream corn and crab flesh just like the “soup jagung manis” recipe.

Then, as I moved here, I replant it in a smaller plastic pot and these are the first two flowers it has since. These photos were taken during sunset… I regret for not able to supply fully bloom photos because there is no way would I want to take photos of it at midnight. I’m so sorry.
